About FieldGemology. org

This website is home for "Shameless Travel Addicted Gemologist" Vincent Pardieu (B.Sc., GGA, G.G.). Vincent is "Supervisor, Field Gemology" at GIA Laboratory Bangkok. He is a gemologist specialized on "origin determination of gemstones".
This is also home for Vincent's regular traveling companions: David Bright, Jean Baptiste Senoble, Richard W. Hughes, Guillaume Soubiraa, Walter Balmer, Michael Rogers, Kham Vannaxay and many others like recently: Philippe Ressigeac, Oliver Segura , Flavie Isatelle and Lou Pierre Bryl.

We are gemologists (gemmologists) sharing a passion for gemstones, gemolology (gemmology), gem people and traveling.

You will find in this website gemological expedition reports and some studies of gemological interest.

Visiting many gem mining areas we saw that people in remote mining and trading areas have difficulties to access to gemological publications. As today the Internet can be accessed in most of these gem mining areas and trading centers, the author started to build this website to give gem people living there the opportunity to see the result of the gemological expeditions they were associated in. It is a way to thanks them for their time and collaboration and to help them to get access to more gemological information.

At the same time the author hope that these expedition reports will please the people from consuming countries interested in gemstones and fascinated by their mysterious origins. Our purpose here is to help people facing difficulties to get quality first hand information about gems and their origins to get the information they need through this website and its links.

With our field expeditions to gemstone mines and gem markets around the world, we intend also here to share our passion for photography, gems and our fascination for the work of the "Gem People" bringing gemstones from the ground to magnificent jewelry.

From the gems external beauty to the intimate beauty of gemstone inclusions, from gem lore to the mines, the people and the landscapes gems origin from, we expect to share with you our passion for gemstone beauty.

We also invite you to join us on some gemological forums we are active in as they are convenient tools to get rapid answers to your questions as they are regularly visited by many other passionate gemologists, jewelers, hobbyists and professionals willing to learn more and share their knowledge about gemstones.

Blog Title: Ten years as a gemologist

In December 2001, ten years ago, the author became a gemologist...

This new blog is a little bit unusual as it is not about a place the author visited recently.

When you plan to visit a mine located on the top of a mountain, there are moments and places where it is nice to stop for few seconds, breath. Enjoy the moment and the beauty of the area. You can have a look down to the valley and study the track you have walked, then you look up to the mine and see what still needs to be done... You may also look inside yourself and feel weather you will be able to make it or not.

This blog is about one of these moments.

Indeed in March 2001, after four months studies, he graduated from the G.G.A. (Gem Genuine Association) in Yangon, Myanmar (Burma) and then in December 2001 after six further months studying gemology at the GIA (Gemological Institute of America) campus in Bangkok (Thailand), he got his G.G. diploma.

10 years... It is long and short at the same time. The author hopes that you will find the following of some interest, even if it is in some way very naive and personal. But may be those willing to study gemology and searching their way into the gem trade will find here some reasons not to give up and find some good advices.

This page is dedicated to them and to all the people who helped and mentored the author during the past 10 years.

Introduction: "Past is Prologue"

The author's gemological studies in South East Asia were the consequence of a long personal quest that the author will present you chapter after chapter in the coming few days and also the beginning of a great personal adventure that will take him to be a gemstone buyer in Burma, a gemology teacher and a lab gemologist at the AIGS in Bangkok, Thailand. Then he will become director of that gemological laboratory. After some work on treatments and particularly the lead glass and the beryllium treatment, he will focus more on origin determination of gemstones starting an ambitious field gemology program to collect reference samples in mining areas. He will then move for 2 years to Switzerland in order to work as a gemologist specialized on origin determination of colored gemstones at the Gubelin Gem Lab in Lucerne. Finally he became GIA's first "Field Gemologist", a position he enjoys each day for the past three years.

Regularly the author is told to be lucky to have such a great job. Well yes. But it was a lot of hard work to become "lucky".

Shakespeare wrote: "Past is prologue...". The reader might possibly wonder why a young countryside French guy like the author decided to study gemology in Burma and then in Thailand? Well as in most cases, there is the long story and the short one.

In the next few days the author will invite you to discover the long one as a series of 10 short chapters (one chapter, one year... 10 years? 10 chapters? Ok, that's a private for a "toon" who might read these lines one day if she has some time to loose). But as not everybody might be interested in the author's detailed long stories, here is the short one: The point is that, even before to get a serious interest for gemology, the author had a deep passion for traveling. Deciding to invest a year studying gemology was a great opportunity to discover at the same time another country, learn not only about gems and gemology but also about gem people, their culture and the gem trade. Now when you realize that most of the rubies and sapphires going into the gem trade weather they are produced from traditional sources like Burma or Sri Lanka or from new deposits in Africa will probably travel one day to Thailand, that choice makes a lot of sense. As I found out later, it was indeed a good move for the simple reason that:

"The gemstone trade is not truly just about sciences, arts, money or even gemology. It is mainly about people."

The author's point is that if somebody is interested in studying wine, the author, as he was born from a wine making family near Bordeaux in France, would recommend him to study in France. Studying wine in Thailand could be great (as studying gemology in France.) but my point is that when you study wine in Bordeaux (or may be Burgundy...), it is a different experience for the simple reason that when you leave your school, you are still surrounded with the wine culture: If you are truly interested in wine, you can then use your weekends to visit vineyards, shop for fine bottles in local cellars, witness the "vendanges" and the following wine making process, meet wine makers and traders, build a network of friends and contacts that might make the difference later for your career, and of course you can also have the pleasure to build your own expertise in wine going for lunch or diner in one of the numerous local restaurants and experiment how good wine is a key component of fine French food and social culture.

In fact while selecting the right place or the right school to study, it all depends on your personality, on the school specificities and your project. If your project is to live in Paris and to find a way to make a career with one of the famous French jewelry brand names like Cartier, Van Cleef & Arpels, Dior, Chanel, Chaumet, Boucheron or JAR then studying gemology in France, few hundreds meters from Place Vendome, might make sense, particularly if you find out that several former students from that school are currently working in the company you would like to join. But if you are more on the adventurer side and dreaming about going one day to buy gems in the jungles and the mountains of Asia or Africa, or if you want more quietly to discover gems and at the same time discover what is going on in these Asian emerging economies, then going to study gemology in Thailand for six months might be a great move.

But don't get me wrong: I don't mean that a "smart" choice that fits your personality and your project will be a guarantee for success. The wannabe gemologist will still need to work hard to be successful: Along the road, there will be positive and less positive experiences, but as I repeated to many young people coming in Thailand to start a career in relation with gemstones:

"You will be able to say that you have failed only when you will have decided to stop trying."

In the author's experience knowing what you want to do and taking some smart decisions will definitively help you to success. It is like preparing an expedition in mountains: To be successful in the gemstone trade you will need to schedule and to finance your studies and may be as it was the case of the author you might have to accept to work at the beginning for a very low salary, just to be able to get the experience you need to complete your profile and enable you to get a better position few months or years later... It might surprise some of the readers but it took seven years to the author, working as a gemologist, to be able to get a position with a salary enabling him to save some money at the end of the month while doing what he likes to do. Gemology is a very competitive business, it is difficult to make a living with gems if you don't have a real professional level, and to get it, there is no choice (particularly if you were not born from a gem merchant family) you will have to work hard and not just hard but also very smart... As we know: "Rome was not build in one day", and with gems, experience is really very important. The author's point is that if you don't take the right decisions, working hard, might turn to be more or less useless. Thanks to his mentors, the author got great advices and was able to make the right choices. Thanks to that he became quite successful in what he was doing. Then one day, when things were not very easy, he got the opportunity to be "lucky"... It had been a lot of hard work to get the chance to be "lucky" that day but it was worth it.

Now let's stop here for a while. Tomorrow and each of the next following nice days, the author will post an additional chapter to that blog telling more in details, chapter after chapter, how was able to combine his passions for gemology and traveling and how he became 10 years ago a gemologist. The author hopes that the next chapters will be found useful for people willing to start something in relation with gems. He also hopes that the people spending some time reading that blog will not feel too much bored by that long and quite complicated story...

"See through the eyes of Jean Marc Aubert, one of the author's friends from his time at Bordeaux Science University, here is a funny game related short biography of the author written in French (sorry for the non French speaking visitors), that was published in 2004 in a French strategy game magazine.

Chapter 1: From the "Black Prince" to Mandalay.

I got my very first interest for gems while reading the novel by Joseph Kessel: "La Vallee des Rubis". It was about Mogok (Burma) and its rubies. That interest increased later while studying sciences in Bordeaux University (France). It was not really coming from my chemistry studies but from something completely different. Besides studying sciences I was actively involved in the organization of LARPs (Live Action Role Playing Games) with a group of friends. I was enjoying working on creating scenarios for fantasy and historical medieval type events. In such aspects I found that gems were of great interest particularly while I was working on a project based on the "100 years war between France and England". Studying in detail the life of one of my favorite characters, Edward of Woodstock, famous as the "Black Prince of England", I came to learn about the existence of the "Black Prince Ruby". For few weeks I did my best to learn as much as I could about that gem. Its history was already fascinating to me but there was something more: It was just amazing to me that what was probably the world's most famous ruby was not really a ruby but actually a spinel... How come? From that mystery came my very first interest for gemology, rubies and spinels. An interest I never stopped studying since then.

I bought my very first gems in Vietnam while traveling in 1997 near Yen Bai on my way to Sapa. I was approached then by a man introducing himself as a farmer who found some rubies in his paddy fields. He told me that he needed money as his wife was sick and needed some medication. His stones were five nice rough waterworned shining colorful gems. It was like candy to me... Few minutes later I had 5 rubies in my pocket and $500 less. The stones turned to be synthetics.

In February 1998, as each winter, I was backpacking in Asia with two of my friends: Christophe Gilanton and Anne Riou. They were not really what we could call members of the gem trade. I met Anne in London while I was studying chemistry in UK in 1995 and Christophe in 1996 while I was studying business in Toulouse (France). Anne is now a school teacher while Christophe is working in IT. We were then visiting Mandalay, one of the former capitals of Burma.

I was excited to visit Burma. One of my projects was to visit Mogok, the famous valley of rubies I read about when I was young. Visiting the gem market in Mandalay I had some fun looking at stones and buying another nice ruby, faceted this one, that I paid $100.

For few days my friends and I took two different paths: They had a visit to Hsipaw while I had an interesting solo adventure traveling to Mogok with U Phone Gyi, a Burmese man I met the day before near the Irrawaddy River. That's a very long story but to make it short I will say that few days after that encounter this U Phone Gyi took me to visit some sapphire mining sites near Mogok. There while speaking about gems with a group of Burmese miners and dealers, they asked to see the stone I bought in the market. I learned then that the ruby I bought few days before was obviously "Pyinthi" meaning "French"... What do you mean by that, I asked? Then the Burmese dealers told me that for more than 100 years French are famous to have discovered the way to make synthetic rubies. Thus the Burmese word for "French" is used to describe synthetic gems. Well that was the second time I got cheated. U Phone Gyi told me then few words I like to remember: I had to be careful with gems as if this gem trade can be seen all about love and trust, there are two nasty devils called greed and ignorance messing with it... It was a nice Asian indirect way to tell me that I had been stupid particularly as it was the second time I did such mistake. These 2 days around Mogok were just like heaven to me, but I had soon to return on Earth and we had to escape from the area. Finally we were able to return safely to Mandalay. Waiting for my two friends to return from Hsipaw, I spent my time with that interesting Burmese man meeting gem people around Mandalay and looking at gems with a focus on his favorite gems: Star rubies and star sapphires. Wonderful days...

Later on our way back to Yangon, while sailing slowly on a merchant boat from Bagan to Pyay for days, I took some time to thing about my life and these recent Burmese experiences. I had some great discussions with my friends about what happened in Mandalay and around Mogok. As it happened several times in my life, while speaking ideas came and suddenly I realized then that gemstones were at the junction of everything I was interested in: Adventure, science, art, history, geography, nature, people... I had nevertheless a problem: So far I was cheated twice. Obviously I had to learn more about gems in order to be able to make the difference between genuine natural rubies and synthetics.

Back in Yangon, I was decided to learn more about gems. Visiting the Bogyoke market, I found the book "Ruby & Sapphire" by Richard W. Hughes. That was exactly what I was searching: The introduction "Something of myself" written by the author was an echo to my own wanderings and the rest of the book finished to convince me: Rubies and sapphires were found in many places I was dreaming to visit. I was convinced: Rubies and sapphires were really the connecting point of all the things I liked. The book became my favorite traveling companion when I was traveling around the world, taking tourists to visit Europe and Asia. Each time I had some time I was taking some pleasure to read again this or that chapter and studying it.

Some people might note that I had then already by bush hat and my lozenge shaped glasses: That was my way to be easy to recognize by the people in my group in order to minimize the chances to loose somebody."

Chapter 2: A French Jeweler in Italy.

The main problem the author had for many years was that he did not really know what he wanted to do with his life. Meeting young (and not so young...) gemology students coming to study gemology in Thailand, I found that he was far to be the only one in such case:

In 1998 after some science and business studies I was working for few years as a full time tour guide specialized on Asia and Europe. I was very happy with my work and FRAM the company I was working with. I had nevertheless the feeling that it was, for many reasons, just a period in his life. Life was then like walking on a mountain. It was nice to visit so many countries and meet interesting people, but I had the feeling that I had not yet found my place. As I had no real goal, something was missing. In other words, as I was very involved in historical and fantasy type LARPs, I was often feeling (like many other young guys) like a wandering young knight searching for a quest that would lead me one day to some princess or some holy grail.

In summer 1999, a year after my expedition to Burma with Christophe and Anne, I still working as a tour guide for FRAM, I remember a specific day while I was traveling with a group of tourists in Italy to visit Venice, Verona and the lakes of northern Italy. For about one year I had an interest for the gem trade and I was searching (quietly...) a way to start something in relation with gems. When I had some time, I was not missing an opportunity to read this or that chapter of my favorite book: "Ruby and Sapphire" by Richard W. Hughes. A French jeweler who was traveling among my group of tourists noticed these readings. The jeweler came to see me and we had a very interesting discussion. It was one of the great things working as a tour guide: It was not only about visiting many beautiful and fascinating places, but it had also often the chance to meet a lot of people. Some of them had very interesting lives and great stories to tell. They were on holiday. I was their guide. They had some free time and some of them were happy to talk. Often these conversations were very meaningful as at the end of their life, few people have any reason to lie to somebody they will probably never meet again. In that case the author does remember that he told the jeweler about his very naive desire to try mixing gems and traveling. The jeweler said that it would be very difficult in his opinion as if there was an easy way to make a living with gems and traveling, then he would not be a jeweler in countryside France. That was not really what I wanted to hear, but it was something I would often think about during the following years...

He had several interesting points:

He said that if just the fact of traveling to the source in Thailand, Vietnam or even Burma and buying there gems was enough to make a good living, then pilots and air hostess would be millionaires: They are not.

Of course he said, I could buy some gems here or there and sell them to my friends but his feeling was that it is quite a dangerous idea to build a business model based on making profits on your friends: Just make a mistake (like buying synthetics as the author already did twice...), sell it to a friend and the result can be a pure nightmare: Everybody will probably find out about it. You might then loose their trust and may be also their friendship if you don't deal correctly with the issue. He was preaching a convinced one, as I never feeled comfortable to sell a stone to a friend: Usually I prefer just to offer them the gem they like... Furthermore, it is also important to understand that gems are not food: After few months, he said, when all your friends will all have bought from you a fine gem, you will need to find other customers because they will probably not need another stone...

Gemstones are not salads, he said, if you don't understand that point: You will fail. That was a very good point I would remind since then and that I recently refreshed in association with on the presentation I gave in May 2011 at the ICA congress in Rio de Janeiro.

But the main weakness he could see in the author very naive project was that the author had no family in the gem trade:

I had Nobody to advise me, nobody to provide me some useful business contacts... No mentor.

He was right: I had a serious problem with that project.
A good book was obviously not enough...
One solution was making a lot of sense: I had to find a mentor.

Well, that's something easy to say but not that easy to find. Mentors accept to advise you usually if they feel that they are not loosing their time with you. I had then not a real idea about what a mentor could be. One of my friends, who happened to be a serious fan of star wars, was enjoying speaking about the Force, Jedi Masters and their padawans,... Basically his vision of my problem was that I was a wannabe young padawan searching for some Master Yoda to teach him the way to use the Force and to help him to stay away from the Dark Side... The reader might think at that point that the author has possibly some mental problems, but rapidly the author found that it was nice to use that Star Wars terminology. Indeed it was fun and clear but the main advantage is that it is not related to any specific religious background. I found it very useful many years later when I started myself to mentor some young gemologists that my old French university friends and myself like to call my "padawans" as I could explain to any of them independently of their personal religious beliefs what I was meaning in a way that would be seen as fun and acceptable.

Returning to the discussion that day in Italy with the French jeweler, I was starting to wonder about who could be my Jedi Master? Who could spend some time advising me?

Immediately one face came to my mind: U Phone Gyi, the Burmese man I met in Mandalay, took me to Mogok and for several days shared with me his love of star rubies and sapphires.

Chapter 3: U Phone Gyi.

I decided to return to South East Asia during winter 1999-2000, in order to meet U Phone Gyi, spend some time with my girlfriend and get some additional personal knowledge of Thailand, its people and culture. After some disappointment with my girlfriend, instead to spend the millennium New Year's day with her, I decided to focus on my quest. I traveled again to Mandalay, alone this time, to meet again U Phone Gyi, celebrate with him the millennium and ask him if he could teach me what he knew about gems and become my mentor...

May be at that point I should introduce you U Phone Gyi. That will be a long story but you might find it interesting:

U Phone Gyi was exceptional to me in many aspects. He was very simple in many ways. He had a lot of knowledge but still a tremendous curiosity. He was one of these people from another time who had a life full on unbelievable adventures and who would tell you about them as you would tell your last Sunday searching mushrooms in the woods near your house... He was a kind of poet with an disturbing fascination for light and darkness. Obviously he had seen, lived and possible done a lot of terrible things in his life. He had many shadows in his mind but he was not loosing as occasion to smile, live and laugh. He was usually very serious in all what he was doing: speaking, looking at gems but also sadly drinking and gambling. Extreme in many ways he was nevertheless often very wise. Very educated he was speaking a very good English and Chinese... Weak in appearance he was tough and sharp like a blade of the best steel. He was one of these complex personalities: A survivor of many dark and few bright days and he used to say... What he was telling about his life was just fascinating to me: According to what he told me, he was from a good wealthy Burmese family from Yangon, he studied zoology at the university as he had a passion for natural things. But he was also rapidly involved in politics and joined the BCP a group of communist insurgents operating in Northern Burma. Then under circumstances that are not clear to me he then joined to the KIA (Kachin Independence Army) and got married with a Kachin woman. He was later arrested by the Burmese military regime and spent 3 years in jail where he told me to have experienced forced labor. At some point in his life, it is not clear to me today if it was before or after his arrest, he also worked as a jade miner in Hpakant (Kachin state) and as a gem trader around Mogok. Thanks to his knowledge about gems, the nature and the areas along the Chinese border he told me that he was making a living as a small gem dealer, buying gems in Mogok or Mandalay and selling them in Mandalay or in China. He was also working as a translator or as a kind of public writer. He was living what was looking to be a simple life in a small house in Mandalay, between with his wife and his lovely 7 years old daughter. As everybody he had also his share of shadows. Many of them in fact... It was what he was calling his dark side. He was not hiding them to me due to the circumstances of our first encounter:

Meeting with U Phone Gyi on Mandalay river banks... On February 13th 1998, U Phone Gyi found me seated at his favorite gambling spot. If I was simply enjoying the morning on the riverbanks of the Irrawaddy River, writing things on my diary, on his side he was coming to gamble with his friends. But as he told me later,

"Your presence was disturbing for us as we were not feeling comfortable with a young foreigner seated at their table and witnessing our shameful addiction to gambling: You see Vincent, as a foreigner, you are a guest in our country and it is our duty to show me a good image of Burma. We could not let you look at us gambling and drinking as we were willing to do..." So he told me that he came to me with as objective to find a polite way to make me leave the place.

He was a nice educated man, and after a short discussion he noticed that I was wondering about what was going on on these islands I could see on the river. There were some people taking regularly small boats to go there. He then invited me to take me there, not to the most busy part of the island as that place was according to him a dangerous place for a foreigner with its numerous opium dens and gambling places, but instead he could take me to visit the nice village on the north of the island. I had time to loose, I was curious, I was enjoying the discussion and despite the idea that may be it could be a trap, I had a good feeling with that man and I decided to trust him and to visit that nice village. Indeed the village was beautiful and we had a great lunch under a huge flame tree. We spend there three hours together speaking about life. I told him about my deception not to be able to visit Mogok, the famous valley of rubies that I was wishing to visit one day. The place was interesting me as I first knew about Burma after reading the novel "La vallee des rubis" by Joseph Kessel but the day before we had to drop our plans to visit it. U Phone Gyi then told me: "Vincent, if you really want to go to Mogok, we can go there together...I know very well the place and have many friends there". That was the start of a long discussion and the consequence was that following day I was with U Phone Gyi on my way to Mogok, an incredible expedition that I see today as one of the most significant turning points in my life. But telling that story would just be too long for that blog.

Regularly U Phone Gyi was abandoning himself to that dark side going at night to the Irrawaddy river, its river banks and its islands... He told me that Mandalay was an extreme city. Hot and sleepy during the day, wise and spiritual at sunrise or sunset when the monks were walking along the streets collecting donations or when people were enjoying the last rays of the sun... but also wicked and dark particularly at night near the port and on the islands of the Irrawaddy River where reportedly opium, heroin, gambling, drinking, sex, sweat, greed and misery where blending with passion. According to him despite these darkness still there was hope. Beautiful, rare and durable, the stars were for him truly the gems of the sky. He had a special love for stars: He told me that when life had been very tough for him, suffering in the jungle while he was with the guerilla, or in jail or loosing himself at night near the Irrawaddy, still he could see these stars like distant symbol for hope. Now if the stars from the sky are impossible to catch, you can find stars also in the most precious stones coming from the Earth. He told me that in rare cases the best rubies and sapphires could also display a star. He was convinced that star rubies and sapphires were truly powerful talismans and in wicked places or during difficult times, it was important for him to have a beautiful star stone as a protection. He believed truly that the reason why he was still alive is that the stars loved him. When I told him that I read somewhere that rubies were symbols for health and strength and sapphires for the wisdom and the soul, his eyes shined and he said: Yeesss!

At the beginning of our adventure, I was wondering if he was one of these common crooks searching for tourists to cheat or if he was really that type of man he told me he was. To be honest, I never really knew if he had been indeed a member of that communist insurgent group, but I had the feeling only a incredible story could have produced such a unique character. And despite many concerns, I had a good feeling about him and I had really great time enjoying his presence.

On December 30th 1999 I arrived in Mandalay to meet him again. The stars were probably also loving me as I had no difficulties to meet him again. We had great time together. We talked a lot. We saw many nice star gems. I bought one of them including a beautiful star gem half pink and half white with very sharp and regular branches: The perfect gem to have to celebrate the passing from the 20th to the 21st century. Indeed I did very well with that little gem on January 01st 2000. U Phone Gyi was very happy and during the following days we started building some crazy projects dealing with nature, gems and traveling. When today I think about them I cannot avoid smiling as I was obviously very naive, but nevertheless it was a great period in my life and I learned a lot...

Chapter 4: A crazy project:

When I came to meet again U Phone Gyi on December 30th 1999, I did not arrived empty handed, I knew his love for star gems and I came with a small precious present: A nice Vietnamese star ruby that I bought during the last visit I had as a tour guide with FRAM in Vietnam. He was very interested by that gem, but not exactly the way I was thinking he would be. The star stone was very nice even if the color was a bit purplish pink. According to him the price I paid for it was not outrageous. He liked the gem, but not only because it was a beautiful little gem, but because he had never heard that quality star rubies could be found outside Mogok. He wanted to know more about the Vietnamese ruby mining areas: Was I able to visited them? No... Why? He asked me. Well, I had no real answer to give him and I was suddently feeling a little bit stupid. He then told me that unlike Burmese people like him as a young Frenchman and I can go everywhere around the world. I was even able to go to Mogok with him... So I could probably go to these Vietnamese ruby mines if I was willing to. If he was me this is what he would do as he was thinking that there could be some very good business opportunities between Vietnam and Burma: If I could find out the source of these gems we could have a good business partnership. Burmese people would pay a very good price for a fine star ruby...

I was feeling incredibly good as the man I was coming to see in order to ask him to become my mentor was more or less proposing to me. As I learned while studying business in France years before: You don't convince people with your arguments, instead you convince them with their own arguments, and you reach the master level when you can set up the things for them to feel that the idea is coming from them. I was just witnessing that. I was telling myself that If I had planned the things, it could not have been any better. In fact I had no hidden ideas with that stone, it was just a present. But a present that turned to be a wise one... The stars were indeed my friends as U Phone Gyi told me regularly! Lucky...

Back to planet Earth, he told me that for our project to succeed I should learn more about rubies. He could teach me about that and also I should learn to speak Burmese, if I could speak Burmese and get my skin more tanned, I could then travel in northern Burma introducing myself as a Gurkha, one of the descendants of the Nepalese soldiers from the British colonial times. The Gurkhas are still living in Burma and particularly in Mogok and many of them are gem dealers. That would be a good cover. For me to learn about rubies, learn Burmese language, get a tanned skin and to get some money, he had an idea that some old friends would describe as quite fun while most of the readers will probably label as completely crazy. But it happened that when he told me about that plan, I was not in Paris or bangkok: I was seated with my old friend near the Irrawaddy river in Mandalay. Everything was different as I was in the Other World, somewhere out of time and reason.

For me to learn all that at the same time, I needed to be able to spend about a year in Burma. He said that this could be possibly done with the help of some monastery. The plan B was more rock'n roll: We could go north in the remote Kachin state where his wife had some family. In that area, he said, there is no Burmese military. I could stay there as long as i wanted and he could teach me about ruby and even jade... I could learn about how to cut star rubies and to speak some Burmese and Chinese. Now to finance that year and our future projects, he had one of the funniest ideas I ever heard. An idea that now I think as "so Burmese...": We could capture some wild elephants and train them. Then when the elephants would be trained we could travel west through the jungles of the Nagaland to India. There we could sell our gems and also the elephants. It could be a good and quite safe way to have a good starting capital for our project and it would allow him also to have enough time to train me quietly about gems, Burmese and life in the jungle as that knowledge would be very useful for the second part of his plan!

The second part of his plan was involving me to go to Vietnam, make some good connections at the mines and get some good star rubies at reasonable prices. With my knowledge about gem cutting I could know how to make the difference between good and bad gems. Then the idea would be to travel from Vietnam to Yunnan and meet there Mr. Lee, one of his old Chinese friends, from the time he was fighting as an insurgent along the border between China and Burma…

May be he is still alive he said. One of my first tasks, he added, would be to find out about that traveling to Yunnan. Indeed he had no news from his friend for several years, but he could write for me his address near Kunming. If I could go there and pay him a visit, I could convince him to join us for that business. He gave me an introduction letter for Mr. Lee and wrote his address in Chinese at the back of the letter. With that he said I should be able to find my way to Mr. Lee after my arrival in Kunming.

At the end of that visit in Mandalay he introduced me to a miner from Mogok who had knowledge of an interesting book being written about Mogok, the man had a flyer about that book: “Mogok, valley of rubies and sapphires” by Ted Themelis. I found that interesting as Ted Themelis was one of the people associated with the chapter about heat treatment in the book "Ruby and Sapphire" by Richard W. Hughes. According to the flyer Ted Themelis was based in Thailand. I took his email, thinking that definitively I had to get that book.

Chapter 5: Kunming: From naive dreams to cold realities:

Back in Chiang Mai, my first idea was to get a visa for China and travel to Yunnan to see if I could meet that mysterious Mr. Lee. May be we could become friends and work together? I had also an interest learning more about China: So far unlike Vietnam, Thailand and Burma, I had only travelled to China as a tour guide, never by myself. Searching for Mr. Lee could be a good occasion to have some personal experience outside the touristic tracks with China… I had an old interest for the Silk Roads, and for years I had the desire to travel one day from Yunnan to Tibet and then to Kashgar. That could be a great personal adventure to visit these remote places that few foreigners visited. I could give it a try as now I had some good reason to go to Yunnan.

On January 27th 2000 I took a flight from Chiang Mai to Kunming. But there things did not happened as expected. First arriving at the airport while waiting at the immigration I was stolen my wallet. Then the letter from U Phone Gyi turned to be a useless piece of paper. After two days showing around the name and the address I was given by U Phone Gyi, it was clear to me that I had no chance to find that man who was possibly dead for more than 10 years in that huge modern looking city with more than five million people.

Kunming at the end of January 2000 was not really what I could describe as a foreigner friendly city. I was wondering what to do? I could try to scout the way to the Burmese and/or the Vietnamese border, but I had also my old dream: Visiting Tibet and going to Kashgar. I was still a tour guide and with my tour operator I took tourists to visit Beijing, Shanghai, Xian, Guilin, Gwangzhou, Hong Kong. Now I was for few frustrating days in Kunming and I was willing to do something different. I was lonely as never I had been as I could not find any friendly person in the city who could speak any of the languages I knew. I got the feeling that it would be nice if I could go to Lhassa and may be from there to Kashgar on the Silk Roads. Reading my old diaries and writing these lines, I'm amazed today about how I was able to get such funny ideas that were not making any sense at all. Anyway, the next day, I found myself traveling on bad roads in one of the worse public bus I ever took. After a night in a scary and really disgusting "shit hole" (Sorry about the vocabulary but honestly I feel that the words are still a little bit soft to describe that place that some of my friends reading these words might rightfully associate with one of the author favorite stories he usually keep for good diners...) I found myself the next morning stopped at a checkpoint. I had no idea about where I was or about what was the problem but I was not allowed to go further. After few hours wondering what was going on at the police checkpoint, the police put me on another bus going in the opposite direction. I had then to spend another night on the disgusting shithole I told you about. Back in Kunming after 3 days for nothing, I was tired, my body was broken after 3 days on bad roads and I had a definition for China in two words: "It Sucks!". Anyway, that was what to be expected when you go to such difficult country as China without even a minimum of planning, with nearly no cash and no good local contact. One of my padawan would call that traveling technique few years later the "Optimization of the luck factor". That day, i wrote in my diary a definition for myself in also two words: "Damn stupid!"

I had only one idea after that complete waste of time: Returning to Chiang Mai and Thailand… The story is much longer and is quite out of subject regarding that blog. But some may find it tasty... So to make it short, the next day I found myself blocked in Kunming for few more days due to heavy snow falls. The people at Thai Airways told me that the plane could not come due to the bad weather. We had to wait for the weather to get better. I was freezing as I had no winter clothes. Furthermore I had not enough money to pay one more night in my hotel. I was hungry and nobody was looking to show any concern about me. After few depressing hours seated on a chair inside the warm office of Thai Airways and wondering what could be my next move, the staff asked me quite roughly to leave as they were closing the office. I was then alone in the snow feeling that I could die in the street and nobody would care about it. Some guys had fun throwing snow balls at me. Thanks to them my pullover became really wet. I asked them to take a photo of us... I was feeling very very cold, depressed, lonely and angry about how stupid I had been to have put myself in such situation. The day was going seriously down, I had just $10 in my pocket and I had to survive for possibly 3 or 4 days here may be more. I had to find a solution as the cheapest hotel in the area was much over my budget... I had then the bright idea to enter one of the best-looking hotels in town: The King World located just near the Thai Airways office. The Force was with me, as I met at the reception an Italian I saw briefly before at Thai Airways. Like me he was supposed to fly to Chiang Mai and was then also stuck here. After few minutes and few drinks, I told him my story and he offered to share his room at the King World with me. Of course I accepted. Suddenly I was feeling again that I was really a lucky bastard! But I had also the certitude that I had seriously to wake up and to be more serious, if I wanted to be one-day successful in my life. No more "Mai Pen Rai" type expeditions: If it is Ok to make mistakes, it is not ok to repeat them. I had been lucky, I had survived... I had now to learn from that failure.

Chapter 6: Books, letters, hope and shadows...

Back in Chiang Mai, I decided not to give up on my projects. I continued visiting gem merchants and jewelers in the area, and went also to send an email to Ted Themelis in order to see if I could buy his book and may be (let's be bold...) meet him in Bangkok.

I was surprised to get very rapidly an answer and on February 21st 2000, I spent half my day discussing with him in his apartment in Bangkok about my experience with U Phone Gyi near Mogok... First he was feeling that probably I never went there, but then as I was able to provide him many details about the village I visited, I was able to convince him. We had then a great discussion. The book about Mogok was not yet finished. He was still working on it. I bought his other book about the "Heat treatment of ruby and sapphire"... I had no money in my wallet to pay it but he let me go with it. It was greeat from him to trust me. Few weeks later he was surprised to receive by the regular mail, a letter from me containing a $100 bank note carefully placed in a sheet of carbon paper...

We remained in contact and in July 2000, on my way again to Burma with three friends (Jerome Garcia alias "Grand Jesus, Julie Capitrel and Ludwig Aymard), I passed to see him before to return to my "other world" as I was then calling Burma. He asked me to help him with something in relation with his coming book about Mogok: I had to hand carry for him two letters to people in Burma and return with some photos to illustrate the book. Of course I was happy to help and I went to Burma with my friends and the two letters. I had no idea yet that these two letters would completely change my plans and probably save my project!

As soon as we arrived in Yangon we took the train to Mandalay. My friends wanted to experience real Burma, I gave them a 30 hours long experience about Burmese railways. It was tough as we sat on hard wood in the ordinary class. In Mandalay we settled in my usual guest house and we went of course to meet U Phone Gyi. I was quite excited to introduce that character to "Grand Jesus", one of my old LARP friends. We found him not really at his best: Shadows, in his eyes, he had. I told him briefly about the Yunnan fiasco and that in my opinion the whole project would probably not be as easy as he was thinking. He was obviously not in one of his best days. He was much more skinny than before. Obviously the dark side was eating him slowly. He was hearing my words more than listening to me. He was not living anymore with his Kachin wife and his daughter, and the elephant project was obviously not anymore a project. Shadows... We talked nevertheless about Mogok. He told me that he was planning to spend some time in the south of Mogok in an area controlled by the South Shan state Army, another insurgent group he had, it seems, some good connections with. He added that one of his good old friends was one of the local leaders of the SSA. A mysterious man U Phone Gyi was... He told me that within few days he was planning to visit that friend and he would ask him if we could spend winter there. From there he said, we could go to Mogok through the jungle (as we did before) and he could teach me all the things I was needing to know about star rubies. I had a bad feeling about all that: May be I was then becoming wiser? I was not thinking so as in the past my feelings had been usually as useful as my thinkings... But that day since the beginning of that meeting I had the feeling that something was wrong, and later my friend "Grand Jesus", told me that he was also sharing that feeling.

Was he going too often and too deep at night near the Irrawaddy in that "Heart of Darkness" of his? I was wondering... Unlike with our previous encounters, this time there was not much of that cheerful complicity I was used to. We were distant... He was here but somewhere I had the feeling that the U Phone Gyi I knew was far away. We left each other too rapidly that day as I was not alone but traveling with three of my friends. I was hoping that I would meet him again few weeks later as I was expecting to return to Mandalay. Hopefully we would have then more time to speak a little further about some projects in relation with gems. I was hoping that we could have again some great time as before when he was far away from his shadows...

I was wrong.

Chapter 7: An opportunity called "U Kyaw Thaung".

After Mandalay we continued our visit of Burma spending some great days in Bagan. Finally we reached Yangon. It was the monsoon and it was raining night and day. Everything was wet. Our money was going seriously down. We had to stay in a cheap hotel near Sule Pagoda were we had to defend our room against moisture during the day and at night against the rats that were ruling the corridors, the kitchen and the bathroom. I was happy to leave the hotel in order to go to deliver the letters Ted Themelis gave me.

The first letter delivery turned to be just a formality: I met the lady at the Bogyoke market and the whole story took less than two minutes. The second one turned to be a very different story: I went to visit a man named U Kyaw Thaung. He was a gemstone merchant from Mogok specialized in crystals specimens and spinels. He was living now very far from the beautiful Schwedagon pagoda. He welcomed me in his house, took the letter from Ted with a great smile and invited me to take some tea while he was asking his nephew to get the photos Ted was asking to publish in his book. As we sat in his living room he said something I will remember forever:

"Let's talk about gems!"

We talked about a lot... After about one hour he came to me with the following proposal: He wanted his nephew to study gemology in English, he would have like him to go to study at GIA in Bangkok so his nephew could become friends with some foreigners, but for Burmese people it was difficult to get a passport and travel abroad. So speaking to me his idea was that he could help me to come to study gemology in Burma with his nephew. I could study gemology each morning with his nephew, spend some time after that at the gem market, then may be learn how to cut star rubies and sapphires and in exchange I could teach him how to better use his new computer. He added that one of his good friends, U Aung Ko had a gemological school near Sule Pagoda called the G.G.A. (Gem Genuine Association). The school was very small but U Aung Ko had a great personal gem collection, one of the best collections of Burmese gems in the country. So studying there I will see a lot of interesting stones... U Kyaw Thaung said that the "Associate Gemologist" diploma at the GGA would take me about 4 months to complete. He asked me to give him a phone call few days later to confirm if I was interested, on his side he will see how things could be possible with the school and the Burmese authorities as for a foreigner staying several months in Burma was not very easy. I said that if that could be possible then I would very seriously think about it but I knew already that I would not miss that opportunity.

I had a very good feeling with the U Kyaw Thaung. He was honest looking, and very friendly. A little bit like with U Phone Gyi at the beginning. There were no shadows in his eyes that instead were sparkling with intelligence. He was looking very motivated by that idea and I had the feeling that he would really do the necessary to find a way for me to be able to come and study in Yangon.

On the way back to Sule pagoda, despite the rain and the depressing moisture, I was feeling incredibly lucky, happy and full of energy. My good star was obviously back! If things were turning fine, to have carried that simple letter to U Kyaw Thaung could become a life changing event, particularly after the Kunming experience that had suddenly become a forgotten story. The idea to come to spend four or may be five months living in Yangon during the next winter was a pure delight as I was truly in love with that country and its gem people. Furthermore , staying in Yangon I would probably be able to visit Mandalay sometimes and meet U Phone Gyi again. Obviously it will be a great opportunity to learn more about Burma, its gems and its gem people. I was feeling back on tracks: New tracks. Good tracks!

Back in Bangkok, I told Ted Themelis about U Kyaw Thaung proposal. He confirmed to me that U Kyaw Thaung was a very nice guy, and that I was very lucky to have been given such an opportunity as, to his knowledge, no foreigner had ever studied gemology in Burma since the colonial times... He added that it would be a wonderful opportunity for me to study there as countries like Burma and Sri Lanka can be seen as gemological "holy lands" with a deep and ancient gem mining and trading culture. Obviously I had nothing to loose as after these five months if I had the feeling that the gem trade was not for me I could return to my life as a tour guide, but in his opinion studying at the source in Burma was a great way to start a career in relation with gems. Music to my ears...

Few days later I phoned to U Kyaw Thaung. He told me that he had arranged the things and that I could definitively come to Yangon as soon as I was ready. I decided nevertheless to return in France to work for FRAM during the high touristic season from August to October as expected by my company. I would be able to save some money to finance my studies and get ready while U Kyaw Thaung would have the time to arrange everything. Then I could return in Yangon to study during winter 2000-2001.

We were both very excited.

Photo: Dorothee Perrot, Dec. 2003


When I asked if I had to bring anything for my studies, he told me that I had indeed to get few tools as gemological tools and books were difficult to get in Burma. He advised me to get to buy the "Photoatlas of Inclusions" by John Koivula and Dr. Gubelin, a book he heard a lot of good things about and also to get the same type of loupe as the one he got recently from one of his best customers: Bill Larson, a famous American gem merchant. That special loupe placed over a torchlight was called a "dark field loupe". That pocket microscope made by GIA was a wonderful instrument to check rubies and sapphires in the field. Using it a knowledgeable gemologist would be able to identify most synthetics and treated stones... That was a very convincing argument for a guy who so far had bought only synthetic stones...

He told me that I could get both of them at GIA Thailand.

The next day I gave my first visit at GIA Thailand. I bought on the spot the "Photoatlas of Inclusions" and a GIA "Dark field loupe"... The book was the most expensive I ever bought and the GIA made loupe was not cheap either. But eleven years later I still use the same dark field loupe each time I go to the field, and the Photoatlas is still one of my favorite book. I've no problem to say that the "Photoatlas of Inclusions" and the dark field loupe were truly with "Ruby and Sapphire" the best investments I ever made.

Back in Europe I continued for few months working as a tour guide and saving as much as I could in order to finance a possible change of career. To be honest I was already saving money for about five years in order to preprare my future and now I had the feeling that I had enough money to invest in studies for a couple of years.

In November 2000 I returned to Thailand. I met briefly Ted Themelis who gave me some new mission to carry on while studying in Burma and I took my flight to the other world...

Some of my friends or members of my family were of course a little bit worried to learn that I was planning to study in a country ruled by a military dictatorship with a really bad reputation. On my side, I was happy as few times before and full of hope in my future.

Chapter 8: Studying in "The Other World"

Arriving in Yangon beginning November 2000, I was welcome by U Kyaw Thaung and his family. U Kyaw Thaung Nephew: Ko Htun Htun and I went right away to register at the GGA.

The GGA School was located near Sule Pagoda in downtown Yangon. It was a small school with two classrooms: Our class with Htun Htun and I were in a small room with Daw Than Myint as teacher. The second class was composed of about 15 young Burmese students. It was very simply furnished and very lively. The focus of the school was to teach to students how to identify gems in Burmese market. Few instruments were available: I remember that we had a demonstration about how to use a refractometer, but then as the school had not enough liquid we never used again that instrument. I was quite frustrated at the beginning but our teacher was repeating us with wisdom that in market conditions, the best instrument we should rely on was ourselves. It was meaning that we should come to the market with as much knowledge as possible, and then we had to learn how to observe the gems in order to put that knowledge into practice. Getting knowledge was fine but getting knowledge and a lot of practice was much better. To emphasis on that every Friday the school was organizing a gemological competition: The only instruments available for the challenge were a 10x loupe, a dichroscope, a polariscope and a glass of water. It was team type competition and we had 10 to 15 stones to identify. It was very fun and helped to motivate the students to learn. Nevertheless the results were quite predictable as the team that had the chance to have Htun Htun as a member was nearly sure to win.

The fact was that Htun Htun as many young Mogok people started learning about gems as he was five years old. He was then going with his grandmother to “Kanase” at the gem mines: There he spent hours searching for nice little gems in the left over or the tailings. In 2000 he was now 25 years old. That was meaning that he had already 20 years of experience with gems meaning that he knew already all the stones by instinct and experience. I was 31 years old and if I knew most of the course by heart my whole experience was more or less limited to the fact that I had been cheated twice... Practicing the gem market game conditions besides Htun Htun was sometimes very frustrating as even if I knew all the theory, if we had let’s say four red stones in front of us: a ruby, a spinel, a garnet and a zircon, then in less than the time necessary to spell their name he was able to identify each gem correctly without instrument just looking at the gem and playing with it and the light in his fingers. For me despite my theory knowledge, they were just four red stones that were looking pretty similar.

"How can you know that this is a spinel?" I would then ask commonly.

"I don't know, Vince. It's just obvious to me". He would typically answer.

Well, that was not really what I was willing to hear. Studying with Htun Htun was a permanent challenge and I do remember of some occasions where I was feeling hopeless. But it was great as Htun Htun was all the time very kind and helpful with me. Practicing each day, I slowly understood how to study the gems and use my knowledge. Working hard each day, never missing an opportunity to see more gems, to meet gem people and learn more, I improved rapidly. After two months of daily practice I was also making a lot of progress and I was not anymore one of the weakest on the Friday challenges.


"The Schwedagon pagoda in central Yangon, few minutes before sunrise."

In Yangon I was living like a chicken: Waking up with the sun and going to sleep when night was falling. The point was that most of the time in the area I was staying, there was no electricity in the evening and at night. My days were starting early around 6am, sometimes earlier when the nearby temple was using its loudspeakers. I was then usually going to Schwedagon Pagoda as the atmosphere there was beautiful in the morning. The place had something truly magic and still now when I visit Yangon I enjoy visiting Schewedagon for the sun rise. I had also my habits at a small restaurant near the huge gold covered pagoda. There they were serving a delicious Mohinga. A typical Burmese fish soup with rice noodles.

I was then usually walking to U Kyaw Thaung place in order to meet Ko Htun Htun, take a second breakfast and get ready to go to the GGA. Usually we were going there using the local bus. It was nice and many Burmese were surprised to see that tall foreigner dressed as a Burmese and going like them studying. The school was usually finishing around lunch time. Usually with Htun Htun we were taking a lunch near the Bogyoke market and from there I was often going to visit its gem market and numerous gem shops. I had soon the habit to seat in front of U Kyaw Wanna FGA Lab. There I was playing chess, looking and learning about gems and crystals. Then I was returning to U Kyaw Thaung place to learn how to cut star rubies and sapphire with U Myint Lwin the cutter of U Kyaw Thaung. I have to admit that I was not very good at that. In fact I preferred to teach him about how to use his computer, speak with him or study stones from his stock. Then after an early diner with all U Kyaw Thaung, I was returning home to study and then sleep as soon as night was falling as I could not read anymore. Life was very simple and my days were quietly busy.

After few weeks, when things were well settled down, I took the night bus to Mandalay in order try to meet U Phone Gyi to tell him about my life in Yangon studying gems. It may sound weird to people reading these lines in 2012, but in 2000 in Burma mobile phones, emails were not very common and U Phone Hyi was not the type of man to have a telephone.

When I arrived at his small wooden house I found it closed and for two days I was not able to get any news from him. I was thinking that I was probably in Mandalay at the wrong time and possibly he went for business to Mogok or the Chinese border. While visiting the jade market on my second day in Mandalay, I met one of our common friends. Asking about U Phone Gyi I learned that my old friend died few weeks ago in a local hospital. Asking what happened to our friend, I was told that he died from AIDS but here that was not something to say in Burma those days: Obviously nevertheless U Phone Gyi was going too much to the Irrawaddy and the shadows finally took him...

That was a shock, as I was never thinking that he could be sick with AIDS. It was also the first time that one of my close friends died from AIDS. But somewhere it was so obvious: His shadows, his desire to live every instant, the fact that he was afraid of nothing. Suddenly with that new perspective, I understood many things about my old friend and mentor.

The shadows took him.

On my way back to Yangon during the 20 hours long travel by local bus, I had the time to think about him, his life, the time we spent together, our projects and my future: Life is short. On that planet we have only a limited amount of time to do what we like, we should not waste any of it doing what we don't except for some very good reason. I was already 31 years old, I was still healthy, but my feeling was that I had nevertheless no more time to loose. I really had to work very hard now if I wanted to be successful in 10 years as a gemologist!

I had definitively also to be careful about the dark side of the Force. I had to stay away from the shadows of Bangkok or of the Irrawaddy.

Back in Yangon, I dedicated myself more than ever to my studies. I was convinced that it was time to work hard and dig my hole. I had just no choice, as if I wanted to get the respect from the local Burmese dealers I was meeting everyday at the gem market, I could not mistake for long a ruby for a spinel.

Living among U Kyaw Thaung family, I realized the chance I had as truly I could not be in a better place than among a gem family to learn about gems and the gem trade. With U Kyaw Thaung, I had a natural new mentor. Thanks to him and his friendship, I was immersed in a wonderful gem culture. For four months, I was not only able to study gems, but I could also meet many Burmese and foreign gem merchants coming to buy gemstones in his house. It was fascinating for me to meet in Burma, in the office of one of their suppliers people like Bill Larson, Hemi Englisher or Andrew Mc Grath. I learned a lot from them comparing the way they were negotiating with U Kyaw Thaung and looking at gems. We often some great discussions and thus I was able to widen my interests and understanding for other gems than just rubies and sapphires. Soon I got a fascination for crystal specimens, for inclusions in gemstones and for spinels... I started to collect small crystal specimens and checking with my darkfield loupe thousands and thousands of small stones from U Kyaw Thaung stock, in order to identify their inclusions using the “Photoatlas of Inclusions” I had invested in, I started soon a collection of rubies and sapphires selected carefully for the quality of their inclusions.

Finally as Yangon was an important gem trading center, I was also able to witness some very interesting events:

First, again with U Kyaw Thaung support, I was able also to attend to the Emporium: The official sales organized by MGE (Myanmar gem Enterprises) of the stones like Jade, rubies, sapphires mined from the government run mines. Besides to auction sales of the government gems, many private Burmese traders were also selling interesting gems. Searching around I found an interesting but unusual star ruby that I bought thinking that possibly I could make a profit selling it later in Paris.

I had the chance to live a small gem rush as in December 2000 we heard in Yangon that several thousands of miners from Mogok and Mong Hsu were moving to a swampy area called Namya, located between Myitkyna and the famous Hpakant Jadeite mines. At that time gem mining areas where out of reach from foreigners, and thus I could not visit Namya. But looking at gems in the market in Yangon and speaking with traders returning from the new areas, I could rapidly learn that the main products were rubies that could be as good as the best Mogok stones. Unlike what is found in Mogok or Mong Hsu the deposit was completely of the alluvial type and thus many other gems were associated with rubies including a very special one that soon became one of my favorites: Namya hot pink spinels. Candy to my eyes...

These were four incredible months.

In March 2001, I finally completed my studies and graduated from the GGA... I returned then from Burma to Thailand with more than just a diploma in my hands and few gems in my pockets: I had now deeply convinced to have found my way and I definitively wanted to go further into gemology.

Chapter 9: Paris, the GIA Thailand and first experiences about gemology in the field.

I returned to France for few months with some stones I bought during my studies in Burma. My idea was to see if the idea to start a business as a gem merchant between Burma and France was making any sense. I had one parcel of 30 small and nice star rubies and sapphires all carefully selectedthat I got from U Kyaw Thaung and also I had the five carats star ruby I found at the Emporium.

In Paris I was joined by one of my old friends from university: Pierre Emmanuel Barba. We were thinking that maybe we could that a gem trading company together: The idea was that I would focus on purchasing in Burma while he would focus on sales in France. The adventure did not started very well as with our first shipment between Thailand and France we got an issue with the French customs. Then we spent two days together visiting gem merchants in Paris and then around Bordeaux. The best we could say was that the test was not really convincing. I remember a particular reaction from a jeweler looking at our star sapphires:

"Vous savez, le cabochon c'est pas folichon!" (the French speaking readers will appreciate...).

The only gem merchant in place Vendome who received us to see our star ruby got suddenly afraid when he learned that the stone had not being properly imported in France and nearly expulsed us from his office. Rapidly we found out that we had still a lot of things to learn particularly about the trading aspects: How to import the stones? How to get paid?

In fact we found out that things were just incredibly more difficult than what we expected. I also found out that it was better not to tell too much about my studies in Burma as such an unusual background was seen as very suspicious more than anything else. In fact soon I found that the best was not to speak at all about it as my Burmese diploma had absolutely no recognition in France. To be able to present myself as a gemologist and to be able to make Parisian type gem traders feel more comfortable with me the best would be to get a gemological diploma with more international recognition that my obscure Burmese one...

Learning about gems in a place like Burma was a wonderful experience. But it was obviously not enough. Back in Bangkok I returned to meet Ted Themelis. I told him about my Parisian adventure and he advised me to study in Thailand at the GIA in order to get a diploma with a much better recognition. In his opinion I could also benefit a lot of these 6 months studies in Thailand to learn more about treatments and synthetics as that was not something that was covered by my studies in Burma. Studying at GIA in Thailand I would have the opportunity to visit regularly the week end gem market in Chanthaburi, the border gem trading centers like Mae Sot and Mae Sai. Furthermore Bangkok itself was a major gem and jewelry trading center with hundreds of gem trading companies located around Mahesak and Surasak areas between Sathorn, Silom and Surawong roads. Finally studying in Bangkok I could attend to the Bangkok Gem Show organized twice a year in February and September by the TGJTA (Thai Gem and Jewelry Traders Association), a great professional show attended not only be local traders but also by merchants from all over the world.

After that deceiving experience trying to sell these Burmese gems in France, I had to take a serious decision: I could continue that project in relation with gems or I could forget about it and continue working as a tour guide. After few more tours with FRAM in Italy and Portugal, I decided that it was better to fail trying to follow my dreams than to have regrets one day not to have at least seriously try. Ted arguments about studying at GIA in Bangkok were very convincing. I sold then most of the things I had in France: My car, most of my books and even one of my hunting bows. Then I took then again a plane ticket to Bangkok to study at GIA Thailand.

Except for short visits, since then I never returned in France.

Arriving in Bangkok I started my studies with great enthusiasm. Studying at GIA was great as the classes were modern, I felt particularly in love with the great microscope we had, that were so much better compared to the old one we had to share at the GGA. The approach and the focus of the studies were very different from what I had at the GGA and thus I was enjoying the class a lot. I was also spending a lot of time after my classes with Ted Themelis. He was my new mentor and I was following his advices as so far they had turned to be great. About twice a month, when I was not too busy with my homework, I was traveling to Chanthaburi, Kanchanaburi, Mae Sai or Mae Sot in order to get some additional experience from the local gem markets. Each time I went alone as my classmates preferred to spend their time partying in Bangkok, going to the beach or were working for their families... Most of them were the sons or daughters of members of the gem trade. I was not. Unlike in Burma, I had nevertheless already some gemological knowledge and I could have fun right away competing with my strongest classmates and particularly Kobi Sevdermish from Israel and Robert Rossberger from Germany. It was very fun. Another big difference between the GGA and my class at GIA Thailand was that at the GGA I was the only non Burmese. At GIA Thailand I do remember that the very first impression I had of my class was: What is that zoo?

My classmates were from Germany, Israel, Lebanon, Italy, Texas, Singapore, Burma, Brunei, Vietnam, India and Thailand. None of us except a young Thai couple and the Vietnamese lady, who had also a French passport, were from the same country. It was just great at the class was at the image of the international gem trade in Bangkok. The focus of most of my classmates was about doing the necessary to get their diploma and enjoying their time in Bangkok and Thailand with their classmates.

On my side, things were very different as I had to find a job rapidly after the end of my studies in order to be able to survive. I spent a lot of time after my class with Ted Themelis, visiting him often. Away from Yangon and U Kyaw Thaung, Ted became my new mentor. We became good friends and he gave me numerous good advices. About a month after the beginning of my studies, in July 2001 he proposed me to join an expedition to Burma he was planning in the next few days: Mogok was still out of reach but the Burmese authorities were now allowing foreigners to travel to the Hpakant Jade mines. On the way we would be also allowed to visit the new Namya ruby and spinel mining area. To reduce the costs of the expedition and help him to collect data, he offered me to join. The opportunity was too great for me to start to worry about the money or my study schedule. Immediately I said YES! As my results at GIA were very good, I was able to negotiate within few days with Christopher Keenan, then Director of GIA Thailand, the possibility to miss the class for one week. Thanks to Chris understanding, I was soon on my way back to the “Other world”.

That expedition was like a journey to heaven for me. Besides Ted Themelis, Hemi Englisher, a very experience gem merchant I met Hemi while studying in Burma, was part of the expedition. He was very interested in Namya hot pink spinels. To go to the Jade mines we had to travelled to Myitkyna, the capital of the Kachin State. To save money I decided to travel by train from Yangon to Mandalay and then Myitkyna. After a two days long epic journey, I arrived just on time to sleep few hours before out early departure from Myitkyna.

We left early in the morning with a joint escort from the Burmese military and the KIA (Kachin Independance Army) one of the former insurgent group that had then a cease fire agreement with the Burmese military regime. We travelled west for half a day to reach Namya. It was quite something for me as the place was the first gem mining area I really visited. In July 2001, about six months after the beginning of the rush, we were the very first foreigners to ever visit the area. To reach the mining area at Seboh we had to travel for several hours through a swampy jungle to reach the mining area. Ted and Hemi were riding an elephant while on my side as I was short in cash I decided to walk like the soldiers traveling with us. Despite the difficulties we reached the mines: I was in heaven!

After Namya we continued on an epic journey to Hpakant and the jade mines on a very dusty dirt road. The track was scary but after four hours as our bodies was asking for mercy we reached Hpakant. As assistant for Ted and Hemi, in the following days I did my very best to help collecting GPS data, photos, videos and samples. We visited different type of mines, from open pit to underground operations. It was impressive and truly a wonderful experience.

Later in September 2001, as Mogok was also open to foreigners, Ted and Hemi proposed me again to join them for another Burmese adventure. Ted wanted to collect more data for the second volume of his book about Mogok. Again as my results at GIA Thailand were very fine, Christopher Keenan allowed me to miss some class for nearly 10 more days to allow me to join that gemological expedition.

After few days in Yangon and Mandalay to prepare the expedition I could finally visit the wonderful "Ruby Land" I was hoping to visit with U Phone Gyi: The very place I was dreaming to visit since the days I read the novel by Joseph Kessel "La Vallee des Rubis". After traveling one day from Mandalay we spent three full days visiting mines from dusk to down with the help of a man that was to become a great friend: Dr. Saw Naung U. Days were long, as we wanted to visit as many mining site as possible, we never stopped for lunches. There was just so much to do before to leave. The days were long and tough but again: I was in heaven!

Thanks to these two expeditions working as assistant for Ted and Hemi, I learned a lot. Not only about Mogok and Burmese gems, but also about gemological expeditions and how to collect data in the field. That knowledge was to become very important few years later when I started my own expeditions to gem mining areas.

In December 2001, 10 years ago, after six great months studying gemology at GIA Thailand, I finally got my G.G.

That was the start of a new adventure as I had then to search for a job.

Blog Title: blog GIA FE14: Chanthaburi, Pailin and meeting the MJP.

GIA FE14 (GIA Laboratory Bangkok Field Expedition 14): March. 19, 2009 - Feb. 21, 2010:


Last week end with Tracy Lindwall, a gemology student from California sharing with the author a keen interest for both gemological and conservation fields, we decided to leave Bangkok to travel to Cambodia to meet in Battembang Stephen Bognard, the CEO of MJP, the Maddox Jolie-Pitt Foundation, a conservation and community development organization with a special focus on the Cardamom Mountains, the moutainous region along the Thai border linking Pailin to lSamlaut. On the way to Battembang, we decided to spend as usual some time in Chanthaburi and in Pailin in order to continue discovering these fascinating gem mining areas and their rich historical background. It was a week end full of surprises.


We left Bangkok to Chanthaburi on Friday evening and spent the night in Chanthaburi.


Chanthaburi (Thailand): The lion and my camera: On Saturday 20th 2010, early in the morning we left of guesthouse near the river to travel to Khao Laem Sing, the mountain located at the mouth of the Chanthaburi river. There we first found the scenic jungle covered Phairee Phinat fort, the small ruin that was more than 100 years ago a small fort defending the entrance of Chanthaboon port with two canons. There we found an old jungle chedi that was built after 1908 during the reign of Rama V as an independence monument to celebrate the end of the 10 years of French occupation of Chanthaburi. The area was desert, it was nice...


Down the fort is a small shipyard. We went to visit it in order to enquiry about our main goal: The famous lion rock which, like a majestic sphinx, seems on the drawings of Henri Mouhot a French traveller who visited the region in 1859 to keep the entrance of the Chanthaburi River. The rock was famous worldwide during the past centuries as before using planes to arrive in Thailand most travelers visiting the country then known as Siam where arriving by sea. Chanthaburi was known then as "Chantaboun" or "Chantaboon". The Chanthaboon lion rock was then a common and well-known symbol of the country. The region from Chanthaburi to Pailin was of some particular gemological interest. It was reported by several famous authors (Streeter, Bauer) as the world's most important sapphire mining area, both for the quantity and the quality of the gems produced at the end of the XIX century and probably a consequent number of sapphire of the jewelry from that period were mined in the region then called "Siam".


We could imagine that most of these sapphires, left probably the region and the country they were mined sailing on the Chanthaburi River and passing then near the majestic Chanthaburi lion of Khao Leam Sing before to leave Siam.


The lion was our objective on that Saturday morning. At the Shipyard we met its owner: Mr. Nuu a very friendly man who run a nice and remote home stay between the shipyard and the old jungle covered fort. He welcomed us, told us very interesting things the area and provided us a small canoe to be able to sail up to the famous rock. The water was quiet, but nevertheless the entrance of a river is not without dangers when you sail on a small canoe with a camera: While I was taking photos of the rock as small wave surprised me. I lost partially my balance and dropped my camera. My Nikon D300 felt into the sea. I had just the reflex to grab it before it to sink too deep in the salted water. Hopefully only the camera felt into the water and our 2 other cameras survived the short but hazardous marine expedition...

(Here is the last photo of my Nikon D300 camera associated with a drawing by Henri Mouhot, A French traveller who visited Chantaboun in 1859)

Back on land we took the road to the Thai Cambodian border where our friend and local contact in Pailin Votha Un was waiting us. We drove then to together to Pailin. As usual in March, at the end of the dry season, the whole region was suffering from the lack of water the hills once covered by green jungle during the rainy season were now covered with ashes. The destruction of the jungle and the forest is a major problem in Pailin region. In the south the Cardamon mountains were still green, but here or there we could see from the road several columns of smoke...


Pailin (Cambodia): Update about gem mining (March 20, 2010): We tried to find the ruby miner we met few weeks ago near Bang Pra Lat village but he was not working as there was not enough water to wash the gem rich ground. Votha took us then to the only place where we could possibly find gem miners during the dry season: Near the river. It was getting late in the afternoon and in all the areas we inspected we found the stream deserted. At the end of the afternoon as we were not hoping to find any gem miner, on the way to Pailin city between the river and Ta Ngan Krom, we saw a mining pit. A miner was digging less than 5 meters from a house just near the dirt road we were driving on. Inside the vertical mining pit, which was less than two meters deep, we found a former Khmer rouge soldier. The man was over 45 years old and one of his legs was missing under the knee. Outside of the hole his wood leg was placed near the tree dominating the mining pit. Seated in the deep hole he was nevertheless very actively mining, filling baskets of river pebbles which were then taken out of the hole by another, yet younger, miner. Both of them were friendly and we started discussing about their work and their life mining gems near Pailin. The old war veteran working as miner explained that he lost his leg on a land mine during the war more about 20 years ago. As a former Khmer rouge soldier, he said that he was not receiving any money from the Cambodian government and had then no other choice than working hard to be able to survive. With only one leg, digging for gems was the best way he found to make some money to survive.

Few minutes after our arrival, a local Pailin gem dealer arrived at the mining site, obviously to buy the production of the day. Today was a different story, I was already there and the production of the old soldier was already in my pocket to become GIA reference samples. There was no problem, it was only about few small stones and the dealer and I knew each other for many years. We spent the end of the afternoon together around the mining pit looking at the production of the day, at what the dealer had collected during the past days and discussing about the life of the people mining sapphires around Pailin.

It was a nice. Then as suddently a heavy rain started we all left in a hurry.

We then drove to Pailin. We found that the small city was dusty with road works. Hundreds of workers were building around and inside Pailin the major road that will link Phnom Phen to Battembang and the Thai border through Pailin. Pailin will then probably not be anymore a small and remote village close to the Thai border but a small boomtown on a major communication axis.


On Sunday 21st 2010, as usual we started our day visiting the small gem market located down Phum Yat temple. There, around some tea and noodle soups each morning between 7 and 9 am most of Pailin gem dealers are gathering to discuss and trade gems. About ten dealers, gem cutters, and gem burners were present. After few minutes an important gem dealer of the region came to meet us. During the French colonial times his grand father and then his father were already gem cutters and gem merchants in Battembang.


On an old traditional brass plateau he presented us a very interesting faceted sapphire:


Sapphires of interest seen in Pailin: The blue sapphire we saw that day is an attractive dark blue coussin weighting around 10 carats. Its color could be described as an even deep dark blue with nevertheless the typical grey overcast commonly found on most large basalt related blue sapphires. The stone was very clean with as inclusions just few tiny crystals, their aspect suggest that the onwer was probably right to say that the stone was not heated. Something very rare in Pailin, where several gem burners are working.


If that sapphire was not the best blue sapphire I was given to see, it was far to be a bad looking stone and taking in consideration all its different aspects including its large size and exceptional clarity, it was probably the best stone the author saw in Pailin after nearly twenty week end expeditions since his first visit in 2004: In Pailin, fine sapphires over 10 carats are extremely rare, so rare that so far I never saw one. The largest fine Pailin sapphire I was told about from reliable source was a fine stone reportedly about 15 carats, but I could not get any details except that it was nice.

Back home I was thinking that if I had seen the same stone at the Bangkok Gem Show in a classic booth from a dealer in the middle of hundred other stones, I would have seen the gem in a very different way. I was not just enjoying a lovely stone, but it was also about the moment, the place, the people and the whole story. Enquiring about the origin of the stone with its owner, Votha and the crowd of dealers who gathered around us, I was told that the stone was found few days ago on the ground at the back of Phnum Yat, the pagoda covered volcano, dominating Pailin. Later I heard another story about another recent find on Phnum Yat volcano: A large sapphire was reportedly found in a piece of basalt weighting about two kilos. A 20 carats rough sapphire was reportedly broken from the basalt and sold separately. Nevertheless a large broken piece of sapphire crystal, weighting probably still around 10 carats, was still present in the piece of basalt (see following photo)


Was the 10 carats faceted sapphire the author saw in the morning the piece that was broken from the basalt? It seems that they were found at the same place at the same period... That would be a lovely story. The author was nevertheless not able get confirmation about it. Nevertheless, the following week end, on March 28th the author returned to see the stones and was then able to see them together and document them. The sapphire in the basalt has, like the faceted stone, a large milky area in its center. Their dark blue color was also quite similar but only a serious study in the laboratory will be able to find out if the faceted stone and the sapphire still in the basalt could have been in the past a single sapphire crystal. Even if we don't know yet if this could be the case, the following photo might nevertheless be of interest for readers.

"Sapphires reportedly from Pailin as faceted stone and as xenocryst in basalt"

(Another photo of the same faceted sapphire in association with the sapphire xenocryst in Phnum Yat basalt. The Phnum Yat volcano is known to be the source of Pailin blue sapphires. Such pieces of sapphire taken in basalt are not commonly found as in Pailin most sapphire mining is performed from secondary deposits resulting from the weathering of the basalts. This sapphire in basalt was the third the author was able to study in Pailin since 2004.)

For more information about Pailin, please visit the GIA Laboratory Bangkok, "Lab Ongoing research - Field Reports Page" where you will find, among several other gemological expedition reports and gemological research pdfs, the following expedition report to Pailin:

Concise Field Report Vol. 01: Pailin, Cambodia: (Dec. 2008 - Feb. 2009) by V. Pardieu
"The Pailin gem mining area in Cambodia. It is a known source of basalt related rubies and blue sapphires since the end of the XIX century. This report provides an update about the current mining there and illustrates the way GIA field gemologists collect specimens at the source."


Meeting the MJP (Maddox Jolie-Pitt Foundation): After visiting the market we took the road to Battembang in order to meet Stephen Bognard from the MJP Foundation, it was the first time we met and we had a very pleasant lunch exchanging ideas and experiences. We spoke of course about conservation and gem mining. It was interesting to listen what was their experience in the region. In Pailin as in East Africa I was able to see that conservationists have some very similar problems. The main issue, there as in Pailin is the destruction of the habitats. Around pailin and samlot the region is still beautiful in the south of Pailin but in the north it is mainly dust and ashes. the whole are is as we could see at each of our visits is facing many threads. For more details, a visit to MJP website might be a good idea:


In 2003, Ms. Angelina Jolie created the Maddox Jolie-Pitt Foundation (MJP) an organization for the conservation of Cambodia’s endangered Cardamom Mountains. Its initial focus of its conservation work was on the protection of Samlaut National Park (Samlaut Protected Area), an area that contains most of the region’s biodiversity: forests, freshwater ecosystems, and endangered species...


We will meet again in the future and try to see if there is a way for Pailin and Samlaut rubies and sapphire to help to protect the gem that are the Cardamon mountains one of the last natural area in the whole South East Asia.


After lunch we left Battembang to return by road to Pailin, then Chanthaburi and finally we returned to Bangkok around midnight in order to be fit to return to work at the GIA Lab on monday morning. Back in Bangkok I got the confirmation that my camera and my lenses were beyond repair. I got also the confirmation that my insurance was useless in that case. That was a very costly week end but well, I will survive!

Blog Title: FE12, Thailand: A visit to Chanthaburi sapphire mines

GIA FE12 (GIA Laboratory Bangkok Field Expedition 12): Feb. 19, 2009 - Feb. 21, 2010:


Last week end with Richard W. Hughes and two gemology students: Tracy Lindwall (USA) and Jazmin Amira Weissgarber Crespo (Germany) we decided to leave Bangkok to return to Chanthaburi in order to visit sapphire mines around Khao Ploy Waen. It was also an occasion to visit again the recently renovated Roman Catholic Cathedral of Chanthaburi. I was informed by French gem dealer Didier Frediani, a true Chanthaburi lover, that it was now hosting a pure wonder: A beautiful new statue of the Virgin Mary of the Immaculate Conception, the mother of Christ. A beauty of gemological interest...

(A detailed view of the Virgin Mary of the Immaculate Conception statue in the Chanthaburi Roman Catholic Cathedral.)

The statue is special as it is a gift to the church from the Chanthaburi Christian gems dealers and goldsmiths community. It is one of the older communities in Chanthaburi composed mostly of people Vietnamese origin. Their ancestors were coming from Vietnam in several waves: The first one was about 200 years ago when Vietnamese Catholics were trying to escape the religious persecutions of the Vietnamese emperors. The second was during the French colonial times when Vietnamese people fled the French controlled Indochina and came to settle in Thailand and finally after 1975 and the Communist victory in Vietnam.

The Cathedral of the Immaculate Conception is the largest church in Thailand. It was built in Chanthaburi during the nearly 10 years of French occupation of Chanthabun (now Chanthaburi) from 1893 to 1904. It was completed in 1909 after Chanthaburi to have been returned to Siam (1904) by the French III republic.


The statue of the Virgin Mary is nearly completely covered with gold, gemstones and enamels... The blue of her cloak is composed of several thousand blue sapphires originating from Thailand (Chanthaburi and Kanchanaburi). Her white dress is made of hundreds of white sapphires from Sri Lanka. Here of there her clothes are also decorated with several rubies from Thailand, gold and green enamels. She is standing on a green globe where the oceans are again a mosaic of blue sapphires from Thailand while the land masses are composed of hundreds of yellow and orange (probably beryllium treated...) sapphires from Songea (Tanzania) and few yellow and orange sapphires from Chanthaburi highly appreciated here as "butsarakam".


The result is a truly beautiful statue that I really invite you to visit if you happen to visit Chanthaburi... Now with the old Bouddhist temple on the top of Khao Ploy Waen volcano, here is another spot of gemological and cultural interest in Chanthaburi for people not willing just to go there only to guy gems and have some good food...

For more info, I invite you to visit the photo gallery on Didier Frediani website about Chanthaburi and its sapphire covered "Holy Mary of the Immaculate Conception".


Thanks Fred for the info, it was worth a visit!


Of course we were not visiting Chanthaburi only to visit the cathedral and its beautiful statue, our main goal was to visit the sapphire mines around Khao Ploy Waen volcano.

The weather in Chanthaburi region that week end was very cloudy and rainy, Chanthaburi is one of the most wet regions of Thailand and commonly the Chanthaburi river is flooding the whole gem city.

We started again our expedition by a visit at the temple on the top of the jungle covered volcano. The night had been rainy. The smell of the jungle was pleasant and the whole region was very appealing with the distant misty hills and mountains surrounding the plain. The air was pure and birds were singing all around us. The weather was cloudy but clear enough for us to study the area around the old volcano. We could find the location of two mechanized mines in production about 1 kilometer on the north of the volcano and spend some time to enjoy the nature and the atmosphere.

We could hear that at least another mine was in operation in the south of the volcano but could not locate it due to the numerous fruit plantations covering the area. After leaving the temple we started our visit by the large mining operation we visited in January, the mine was not in production as the miners were working on the maintenance of the operation and were moving the machinery. It was still very interesting to see that they had been very active during the past 2 months as was indicating the enlarged size of the mining pit. It was not surprising as we were now in the main mining season around Chanthaburi.

After visiting this large mine we went to visit one of the mines we saw in operation from the top of the volcano. The miners were very friendly and we decided to spend some time there looking at stones, taking photos and discussing with the miners. The miner happened to be a shrimp farmer from the south of Ban Ka Cha. As the price for shrimps were not very high and as there was not much work in his farm, he was using his machinery to mine sapphire in the land of one of his friends. Sapphire mining was for him and his family a way to get some additional income and, he admitted, some fun... We left the miners for lunch and returned later to witness the harvest and collect some reference samples for the GIA Gemological Laboratory reference collection.

That day spent with Thai miners was also a great occasion for Tracy Lindwall and Jasmin Amira Weissgarber Crespo to discover the variety of the production of these interesting mines: Blue, green and yellow sapphires but also black star sapphires with 6 rays golden or white stars depending if the stone is a yellow or a blue sapphire and the rare 12 rays star sapphires. Besides that they could see that the mine was producing also zircons, red garnets, augite (pyroxene), some old rusted objects and even few used gun bullets...


It was a nice week end, interesting and full of surprises.

One thing is sure: We will return to Chanthaburi...

Blog Title: FE11 Thailand, A visit to Kanchanaburi

GIA FE11 (GIA Laboratory Bangkok Field Expedition 11): Jan. 22, 2009 - Jan. 24, 2010:


With two gemology students: Tracy Lindwall (USA) and Jazmin Amira Weissgarber Crespo (Germany) we decided to have a week end field expedition to the SAP sapphire mine in Kanchanaburi. The purpose of the field expedition was to get an update about sapphire mining around Bo Phloi in Kanchanaburi and for Tracy Lindwall to advance on her personal project regarding "conservation gemology".

(The SAP sapphire mine main washing plant in 2005, it was then still in operation with more than 100 trucks bringing gem gravels to wash every day.)

The interest about the SAP sapphire mine in Kanchanaburi is that it was a large scale sapphire mining operation believed to be for years the world largest sapphire mine. The SAP investors were former tin mining entrepreneurs from Kanchanaburi region. Due to the low prices for tin at the end of the 1980's and the new sapphire finding near Bo Phloi in Kanchanaburi in 1978, they decided to move from tin mining to sapphire mining as they could use for sapphire the same equipment they were using for tin.


SAP Mining Co. Ltd started its operations in September 1987. The deposit is located in the Lum Ta Phoen Basin which was covered by lavas coming from the fault zone in Ma Kah Creek about 3 million years ago. There sapphires, black spinel, pyroxene, red garnet and zircons were mined under 7 to nearly 20 meters of overburden.


What was interesting at SAP is that from the beginning of the sapphire mining was planned in order for the land to find a use after sapphire mining will be finished in the area. The water used at the mine was processed with several sedimentation basins before to be released and a several projects including agriculture, fish farms, golf and resort were put in place for the day sapphire mining will not be anymore profitable.


During our last visit in Jan 2010 we were informed by the SAP staff there that sapphire mining had completely stopped in 2009. Now the only mining activity remaining is for construction and decoration material and the company is focusing on the extension of its "Blue sapphire" golf resort. A clever way to use the former mine landscape with its numerous deep lakes and hills.

We went to visit the former mining area. We could see that the former washing plant, which was still in use in 2009 when the author last visited the area, was now abandoned and that there were some important works all around the area in order to develop it into new directions. The area was still beautiful and green with many birds looking to enjoy the lakes and the water.

Finally after lunch we decided to return to Kanchanaburi and as we still had few hours we decided to visit what has become one of the most famous attractions in Kanchanaburi the Indochina Tiger conservation project at Wat Pa Luangta Bua Yannasampanno.


It was a way to prepare ourselves for the coming Year of the Tiger and finally see with our own eye this temple and its tigers. With its growing success entrance fees had become much higher and the project is now becoming quite controversial. As usual the best way to get an idea was to go there and see with our own eyes. The difficulties the monks are facing seem to be very important: How to feed the tigers and to keep them healthy? To give them a decent place to stay? But may be most of all: How to handle the success of the temple? How to give to the hundreds of tourists visiting the temple everyday what they want? Most of them have no idea about how to get close to a tiger and see them as big cute teddy bears... It is obviously not easy to get enough experienced and trained staff to do that, and of course obviously the temple needs new infrastructures to handle its success: Entrance fees are going up and at the same time controversies about greedy monks making money with tigers... Not easy. Not much about gemology here but it was an interesting visit nevertheless...


So to all of you, happy "Chinese New Year" and have a great year of the Tiger!

Blog Title: FE10, Thailand and Cambodia: New Year's Day visiting ruby and sapphire mines near Chanthaburi and Pailin.

GIA FE10 (GIA Laboratory Bangkok Field Expedition 10): Dec. 30, 2009 - Jan. 02, 2010:


With two veterans of the recent expedition to East Africa: gemologists Jean Baptiste Senoble (France) and Lou Pierre Bryl (Canada) we decided to celebrate 2010 New Year's Day far away from the party crowds and close to both gems and nature. On December 30th 2009 we left Bangkok to travel to Chanthaburi, the former Chantabun of the XIX explorers and one of the most active gem trading centers in Asia.

The idea for that short week end field expedition was to get an update about sapphire mining around Chanthaburi and about ruby and sapphire mining around Pailin in Cambodia, at the same time it was a good occasion to travel with some new "padawans": Tracy Lindwall from USA and Neil Doohan from Switzerland, two fans of who contacted me after deciding to study gemology in Thailand as I did also few years ago.

Tracy was looking very motivated to help me on the "Conservation Gemology" project and during the next expeditions around Bangkok she will focus on such issues as ethical and conservation gem mining.

On December 31st we visited the sapphire mining area near Khao Ploy Waen and Ban Ka Cha few kilometers from Chanthaburi. The area was quiet but around ten mechanized sapphire mining operations were visible around the lovely jungle covered volcano and its old pagoda. If most operations were stopped during the New Year weekend, we could nevertheless see two mines in operation and speak with several miners. All the mines in the area are working to produce black star sapphires, some blue sapphires but the main production is yellow and green sapphires, which are later turned into bright yellow/orange sapphires (Locally called "Butsarakam") after heat treatment usually using the "beryllium" technology.

After visiting the lovely area around Khao Ploy rich not only with sapphire mines but also lovely houses and fruit plantations, we were joined in the evening by Neil Doohan, a young Swiss American studying gemology in Bangkok. After a great diner near Chanthaburi River, we decided to return to Khao Ploy Waen volcano to reach the old pagoda on its top and wait there for midnight to come.

At midnight, standing on the top of the volcano, which is the source of all the sapphires in the area, we could enjoy the fireworks all around in the plain... Simply nice!

On January 01 2010 we left Chanthaburi and Thailand by road to Pailin in Cambodia, a small Cambodian city we like to visit regularly despite its bad reputation for land mines and malaria (July 2009 and more recent) as it is an interesting ruby and sapphire mining area not very far from Bangkok. Pailin is located just north of the Cardamon Mountains one of the most interesting and endangered ecoregion of South East Asia. For some background information about Pailin and its gems, please download the "Concise Field Report Vol. 01: Pailin, Cambodia" on

In Pailin we met our Cambodian friend and guide: Votha. With his help, we visited several small ruby and sapphire mining operations around the city. Mining was quiet as most of Pailin population was busy with maize harvests:

Near Bang Pra Lat, we could meet a team of five miners we met last year at O Beng. As last year they were mining rubies with a small old jig and some high-pressure water. During the last month they produced few small rubies including an interesting stone about 3 carats rough.

In another area near Suan Umpal we met two groups of old men mining sapphires with iron sticks in holes in an area that was mined by Thai companies during the "Khmer Rouge" period. Finally near O Ta Prang we met a man and his wife mining in the river for sapphires. Near them an 83 years old Cambodian woman living usually in California, and currently spending some holidays with her family in Pailin, was also enjoying searching for zircons and sapphires in the stream with one of her grand sons.

The visit was interesting as we could add to the GIA reference collection the daily production of the miners composed of several small rubies and blue sapphires.

Our main surprise was to see how the city had changed in just few months as the new road built by a Chinese company linking Battembang to the Thai border had reached Pailin. The new road and the fact that Pailin is became a full Cambodian province since December 28th, 2008 has turned the small sleepy village into a small boomtown.

On Jan 02nd, 2010 we visited Pailin gem market near the Phnum Yat pagoda were we met again all the usual traders and miners. Very few stones were visible at the market as the dealers said that there was very few mining during the past days.

(A small parcel of rough blue sapphires seen at the Pailin gem market on January 02nd, 2010

Around noon, after a short lunch at Samaki market, we returned to Chanthaburi where we could see that the traditional weekend gem market was very slow. Nevertheless we could see many rubies reportedly from Mozambique including numerous large "paw mai" (lead glass treated) and several parcels of small-unheated attractive faceted stones. We returned then to Bangkok in the afternoon.


It was a short visit but it was interesting to visit again Pailin and Chanthaburi after several months away in East Africa and it was a great occasion to meet and spend some time with Tracy and Neil.

Blog Title: FE07: Thailand: Searching for the last ruby mine of Thailand!

GIA FE07 (GIA Laboratory Bangkok Field Expedition 07): Apr. 24 - Apr. 25, 2009: Khao Ploy Waen and Bo Rai
Last week end we decided with Richard W. Hughes to continue scouting the former gem mining areas in the Chanthaburi - Trat province. Our goal was this time to visit again the places around Bo Rai Richard visited at the end of the 1990's when he wrote for his website: an article about the Death of the Thai ruby. (Note from the author: After this join expedition Richard W.Hughes recently put online an update of that article: "Red sky at Dusk: Hunting the last Siamese ruby miner".) For that new week end expedition we had as travel companion two veterans from our expedition to the Phnum Trop volcano near Pailin (FE04): Philippe Ressigeac and Olivier Segura: Olivier and philippe just finished their gemological studies at GIA Thailand.
We started our expedition with a visit as usual around Khao Ploy Waen. There we were able to visit and spend some time at two small mechanized sapphire mining operation. It was nice to meet the mine manager, an English speaking and very friendly character with a big black star sapphire ring and many gold amulets as necklace!

(Details on the black star sapphire ring of the Khao Ploy Waen mine owner: The stone was reported to have been mine here. Photo: V. Pardieu / GIA Laboratory Bangkok, 2009)

After visiting Khao Ploy Waen we left to Bo Rai. There we started to enquiry about any remaining gem mining area, local people told us to go near the Cambodian border, there may be we could find something. We drove on the road Richard took several years ago while searching for the last ruby mine of Thailand at a time when, along the Thai-Cambodian border, the "Khmer rouge" were still fighting the Cambodian government and its Vietnamese allies. Richard was then stopped by the Thai military and could not see the gem mining there. This time if we saw and passed many military check points, nobody stopped us to go further to the border. Driving on dirt roads through the mountainous jungle we saw many signals warning us about mines... A bamboo cutter, who lost his leg in the area, confirmed to us that these signals were not here for decoration or to warn "travel addicted gemologists" visiting the area about ruby mines: They were here to warn about land mines which are still numerous in the area.

(My travel buddy Richard W. Hughes and one of the red "danger mines" signals we saw all along the dirt road cutting through the Thai jungle near the Cambodian border... If ruby mines are not dangerous, land mines on the other hand are with malaria one of the nasty threads of the area.

Finally as the mountain road was too steep, we had to abandon our "songteaw", the typical small pick up we hired in Chanthaburi to take us around. We continued then walking to the border where we met few friendly soldiers who gave us some useful information for our quest: There was nearby one place where people were probably still searching for gems: A place called "Pai Khwai". Asking regularly our way to different groups of local people cutting bamboo in the forest we found our way to "Pai Khwai" which turned to be a cashew nut plantation. There we stopped as there was no way to go further and we started to speak with the people working at the plantation. Two guys got immediately excited and told us that they were indeed searching for rubies each day. Sadly it was already late in the afternoon and they had finished their day. The good point was that we could see and buy their production and that we will be able to come back one of these week end to get more samples directly from the mines for our studies at GIA. They were very friendly and were working here for 5 years going once or twice a month to Bo Rai in order to sell their gems. They were working using very simple hand tools: An iron stick and a hand made sieve... Ruby mining was for them a good way not to loose their time, a way to get an additional income as we commonly saw in many parts of Asia and Africa, and a way to have a chance to find some good stone and to eventually become rich! "Hope" is everywhere the gem miner's mistress... and "hard work" his daily life!

("The last ruby miners of Thailand", a Cashew nut plantation worker present us the small rubies he found that day in the area. Photo: V. Pardieu / GIA Laboratory Bangkok, 2009)

They were possibly the last ruby miners of Thailand: Richard W. Hughes was able to add and end to his old story about the last ruby mine of Thailand and I had some good samples to bring back at the GIA lab. We will have great time studying them. Great week end!

Here is a link to the story Richard W.Hughes put online on his website after that visit near the Thai Cambodian border to searching for the last ruby miners of Thailand.
"Red Sky at Dusk: Hunting the Last Siamese Ruby Miner" .

Hoping that you will enjoy it as much as I did!

Blog Title: GIA_FE06: Thailand: A visit to Kanchanaburi sapphire mines

GIA FE06 (GIA Laboratory Bangkok Field Expedition 06): Apr. 04 - Apr. 05, 2009: Kanchanaburi
That week end again I decided that watching TV or working on this website would not be a good option. It was time to continue my visits of Thailand sapphire mining areas for the GIA.
"Monday to Friday at the lab, week end in the field!", this is a field gemologist type week. Something nice also as it enable the field gemologist to travel with few motivated friends and make the whole thing more pleasant and more efficient: With Richard W. Hughes, his wife Wimon Manoratkul, Valentina Petri, a young Austrian gemologist from Vienna and Raphaelle Delmotte, a young French girl working in Bangkok, we decided to leave Bangkok and spend the week end visiting sapphire mining areas around Kanchanaburi.
We drove to Bo Phloi, the small mining town 30km in the north of Kanchanaburi to visit the SAP sapphire mine. During the end of the 80's and the 90's, this mine was one of the largest sapphire mines in the world. It is something very unusual in Thailand where most of the gemstone mining operations were small scale mining. The SAP Company is an important industrial mining company which decided to mine gems. Again to have Richard W. Hughes with me was very interesting as he was the first to report about the SAP large scale mining operation when he visited the area as he noticed at the end of the 80's that many unusual sapphires appeared in the Bangkok gem trade. Wimon presence was also great as even if Richard and I can speak some Thai, to travel with a gemologist fluent in both Thai and English is really nice while meeting people at the mines. An when this gemologist is also an excellent photographer, and a great travel companion then the whole stuff turn into a dream team!

(A view over the mining operation as we saw it at SAP mine. The machines were then mainly removing the overburden to be able to work later th sapphire rich layer located 20 meters deep.

The mine is much less active as in the past and the former mining pits were turned into lakes and their surroundings into a lovely golf and a week end resort. We could nevertheless witness some mechanical mining with excavators and trucks, but the miners told us that now due to the high cost of gas and to the fact that the best places were already mined, most of the income from the mining was not coming anymore from the sapphires but from the sand and the other construction material. Nevertheless, sapphire mining was still active and a huge washing plant was processing the gem rich ground bring by the trucks.

(A security guard is watching the workers picking sapphires on the belt at SAP mine, Kanchanaburi.

Further at the mine sorting house a group of workers were sorting the sapphire rich gravels on a mechanical belt... Besides sapphires the mine is know to produce a lot a black opaque spinel (locally called "nin") and some zircons. We saw few sapphires that day as they were then sorting the big gravels: Most of the mine was reported to be currently composed of small stones. But Kanchanaburi is known to have produced many sapphires over 50 carats.

(A French girl and a Thai stone: Raphaelle Delmotte holding a small blue sapphire from Kanchanaburi.

After that visit we returned to Kanchanaburi and visited a little the area around the famous bridge over the River Kwai. Besides few genuine gemstones a multitude of vendors were selling mainly imitations and synthetics were, a real nightmare/wonderland for gemologists willing to train their skills!
All the best,

Blog Title: GIA_FE05: Thailand: A visit to Chanthaburi - Trat ruby and sapphire mines

GIA FE05 (GIA Laboratory Bangkok Field Expedition 05): Mar. 13- Mar. 15, 2009: Chanthaburi
This week end with Richard W. Hughes and Mike Rogers I went to visit the former ruby and sapphires mining areas of the Chanthaburi and Trat region. The idea was to try to see if there was still some residual mining activity, make a good map, speak with local people and to try to collect some samples from each area. It was a very interesting week end with Richard as a guide as he used to come to visit this region when there was some very active ruby and sapphire mining during the 1980's and 90'.
We started on March 13th to scout the area around Khao Ploy Waen and Ban Ka Cha. Nothing new, we do that each time we visit Chanthaburi as the countryside around Ban Ka Cha and Khao Ploy Waen is just beautiful and as the area is the main area Chanthaburi where there is some significant gem mining activity nowadays. The sapphire mining area is located around Khao Ploy Waen volcanic dome: a jungle covered volcano hosting a lovely Bouddhist temple from which we could see the countryside with its sapphire mines, its fruit plantations and the nearby coast with its numerous shrimp farms. Driving around Khao Ploy Waen we could see around ten mechanized mining operations.

(A view from Khao Ploy Waen temple over the sapphire rich countryside and the coast:

On March 14th we took the road to the North East visiting the villages of Tok Prom, I Ram, Ban Nawong and Bo Nong Bon. As expected we could not witness any mining activity but we could see from time to time some interesting stones (like the dark blue sapphires of I Ram village) and some colorful and welcoming people.

(A miner from I Ram presents a dark blue sapphire reported to have been mined around the village.

Visiting Chanthaburi Trat region countryside during the week end is usually a very nice experience: The villages were full of people, and the formers Thai miners were enjoying the week end with their families. Thai kids were all around as curious about visiting "farangs" as about the gems of their father!

Again a good week end expedition even if we could not witness any mining except around Khao Ploy Waen.
But we saw some gemstones and many gem people!

Here is a link to a very nice photo gallery by Richard W.Hughes and Winon Manoratkul which was put online after Richard and Wimon expeditions in the countryside near Chanthaburi inlcuding the FE05 expedition we had together:
"Red and Blue: Chasing history in Chanthaburi & Trat"

Hoping that you will enjoy it as much as I did!

Blog Title: GIA FE01: Thailand, Cambodia: Scouting for rubies and sapphires around Chanthaburi and Pailin

GIA FE01 (GIA Laboratory Bangkok Field Expedition 01): Dec. 18- Dec. 20, 2008: Chanthaburi and Pailin!
For my first "week-end" type Field Expedition since my arrival at GIA Laboratory Bangkok, a visit to Chanthaburi (Thailand) and to Pailin (Cambodia) was making a lot of sense: From 2001 to 2007 I visited regularly Chanthaburi and Pailin which are very interesting areas to visit in my opinion for any gemologist visiting Thailand.
It was a good occasion to start doing some good field work close to the lab, to get a first hand update about the ruby and sapphire mining there and to visit again old friends.
For that expedition Stephane Jacquat a gemologist from Geneva (Switzerland) joined me. It was a real pleasure to travel with him:

We visited a mechanized sapphire mine just down Khao Ploy Waen temple just few kilometers away from Chanthaburi. This mine and the others in the area are known to produce black star sapphires, blue sapphires and yellow sapphires locally known as "Butsarakam".

After this visit we travelled to Pailin in Cambodia. During 2 days with the help of my friend Votha we were able to visit the local gem market and to witness sapphire mining inside Pailin and ruby mining in O Beng area and to after witnessing the mining we could collect some interesting samples directly out of the jig for the GIA reference collection.

(Here is one of the most interesting piece we saw that day: A milky blue sapphire crystal presenting a trapiche structure.

This first Field Expedition for GIA was a very successful one! It was also very nice to see again the Pailin gem miners and dealers.
