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.

GIA FE16 (GIA Laboratory Bangkok Field Expedition 16): April 08th, 2010 - April 15th, 2010:

 

Introduction to the Vietnam Luc Yen 2010 expedition: The GIA Laboratory Bangkok Vietnam 2010 field expedition was planned with the support of Dr. Pham Van Long from the Vietnam National Gem and Gold Corporation. After visiting pearl farms in Ha Long and Bai Tu Long Bay with my colleague from GIA Lab Bangkok Nick Sturman and Kham Vannaxay, the author plan was to continue to the mountainous district of Luc Yen located in the province of Yen Bai, in the North West of Hanoi, about five hours driving on the way to the Chinese border.

The expedition had been prepared by the author and a young French gemologist who studied at GIA Thailand in 2009: Philippe Ressigeac. Philippe, following the advices of the author, left to Vietnam in January 2010. There he took few weeks to learn some Vietnamese in Hanoi and then travelled to the Luc Yen gem mining area. In Yen The, the capital of the Luc Yen district, thanks to his skills speaking a bit of Vietnamese he was able within few days to become friend with Mr. Shuan a local gem broker who had an excellent knowledge of the whole mining areas but who, as most people in Yen The, was not able to speak English or French. Few weeks after Philippe arrival in Vietnam, Lou Pierre Bryl, another young gemologist (from Canada) who used to travel a lot with the author joined Philippe. Rapidly the region and particularly its blue spinels mining areas had no more secrets for them.

For that new expedition to Vietnam, besides Philippe, Lou Pierre and Mr. Shuan the author selected some additional very motivated young gemologists:


- First two intrepid young women who just finished their gemological studies at GIA Thailand: Tracy Lindwall (USA) and Jazmin Amira Weissgärber Crespo, (Germany). They had already some experience about gem mines visiting ruby and sapphire deposits in Thailand and Cambodia with the author and besides the motivation to discover Vietnam and its gems they wanted to show to the author that they could be fit for longer summer time expeditions to African gem deposits.
- and also two young French geologists/gemologists: Herve Rezo and Pierre Hemon, studying the DUG (Diplome Universitaire de Gemmologie) in Nantes University with Prof. Emmanuel Fritsch and Dr. Benjamin Rondeau and willing to get some field experience in relation with gemstones and gem mining.


With these six people, the author had a very motivated team. Each member of the group was assigned responsibilities over a specific task. One had to take care about accounting, others had to collect all the GPS data, take photos or notes about the geology while another one would focus on the stones. The objectives for that new expedition were to complete the work done previously by the author on rubies and spinels from North Vietnam: After visiting the area two times in 2009, the author had gathered a lot of information about places that he had not yet the opportunity to visit. Besides training some new young gemologist for possible longer expeditions in Africa returning to Vietnam was a great opportunity to complete some unfinished business, meaning going to visit these mining location he heard about, meeting miners there and collecting data and samples in order to get a better idea about Vietnamese gems. Our main objectives were of course rubies and blue spinels.

 

After that expedition a short update about ruby and spinel mining in North Vietnam was published in the Gem News International section of "Gems & Gemology" summer 2010 issue (Vol. 46, No. 2)

Furthermore Jean Baptiste Senoble, another young gemologist who travelled with the author in Vietnam in 2009, was then able to complete an article for the ICA InColor magazine using the additional information about blue spinels mining siteswe provided him. "Beauty and Rarity - A Quest for Vietnamese Blue spinels" by Jean Baptiste Senoble was published in the summer 2010 issue of ICA's InColor Magazine.


Now I would like to share with you some interesting parts from that adventure using few photographs we took during the expedition:


Part 1: Yen The Morning Gem Market: Each morning from 7am to about 9am most of Yen The gem merchants go to a small square near Yen The Lake to meet people, friends and get the news. Many ladies with beautiful hats will gather and present few stones on small wooden tables while men will come around to check them and may be buy some. But the market is not limited of course to that small square. People from all the areas: miners, brokers, merchants will come to meet each other. Modernity with its mobile phones and motorbikes has of course changed things but nevertheless people still like to gather there each morning: Usually after few minutes looking around and discussing a bit here or there, we were moving to a small open air coffee and tea shop located just near the lake about 100 meters from the main market. Usually we were not alone, the next tables were commonly used by miners and traders discussing business or other matters... Gem markets as this one are a real pleasure for the author as if it is not the place where obviously you will see top quality gems, usually you will enjoy meeting there many gem people:

But Yen The is not just about morning gem markets. During after visiting the market most dealers will return to their house and work. The area around the lake is of particular interest as many gem shops and small family type factories are located there.. Typically in Yen The, people are living and working at home: the lower part of the house usually open to the street and is dedicated to gem business while the family lives in the back or the upper part of the house. People can be seen working on gem painting or cutting and polishing stones from dusk to several hours after down... One of the interesting activities that has developped continuously since the author first visit in Yen The are "gem Paintings". During our visit in 2010 we could see more than ten houses-factories working until late. The production of these gem painting will then get exported all over Vietnam mainly to supply the local market. In Vietnam as houses are often designed and decorated following geomancy rules (a local version of the Chinese Feng Hsui) there is a strong demand for stone carvings and gem paintings.

Part 2: Hunting rubies and blue spinel in Luc Yen jungle covered mountains: The main difference between hunting and hunting for gems is that going to a gem mine is usually easier as if there is a gem mine there is probably a path to visit it as miners will regularly travel from the mine to their village. Nevertheless it does not means that all gem mines will be 5 minutes walking from a given village. Sometimes and this is particularly true for the most remote mining sites in the Luc Yen district of North Vietnam, you will need to get ready for several hours walking on tricky jungle covered mountains.


During the 2010 GIA Laboratory Bangkok field expedition our focus was for five days to try to visit some of the most remote gem mining locations we heard about. Places that the author had not visited yet during his two previous expeditions in 2009 where he focused one the main mining locations at that period. We also tried to find out if there were some other mining areas still unknown to us. The difficulty for people willing to collect reference specimens in order to build a good reference collection is that one should not only focus on where many people are mining today but also on the places where many stones were produced in the past: Sometimes there is still a little bit of gem mining there by few small scale miners and thus going there might worth a visit as some interesting samples can still be collected from them. Small less known or completely unknown sites have also their interest as possibly these areas might produce many gems in the future. Thus each mining site, whether its current activity is high or low, might be interesting to visit in order to get as many interesting samples as possible, from as many different places as possible in a given mining area. Working that way enable to get a better idea about the whole region, the variety of the gem it produces, its challenges and its potential. In the Luc Yen district there is indeed a lot of challenges and potential as the more we were visiting these mountainous area the more we understood that the whole region is rich in gems. In fact the main question for the local miners is not really to find a place where there are gems but to find out if it is profitable to mine here or there. In the Luc Yen district about 20 years after the discovery of rubies in the region, most of the easier gem mining areas (meaning the secondary deposits located under the paddy fields near the Yen The town) have been mined out. In 2010 we did not saw any mechanized mining in the Luc Yen district. The most modern gem mining operations were consisting typically of a team of about 10 miners working with a small pump and a locally made jig. In fact as the author writes these lines, gem mining is present in many remote areas where it was not (or will not be) easy to bring mining machinery. The production is low as fine large gems are very rare, but in Yen The, besides the market for fine gems there is with the local gem painting industry a market for small and low quality stones. To the author experience this is one of the things that explains why there are hundreds of small scale gem miners in the Luc Yen district: Not only the fine exceptional gems can get a market but also all the rest of the production, from tiny gems to low quality large stones. Thanks to that miners will get some income even if they dont find some fine gems. Not much but enough to keep them mining. Thanks to that once in a while a good gem is produced here or there... In many other gem mining areas the author visited the main problem is that there is no market for very small or low quality stones, thus people get hopeless with their production that cannot find any market. As a result soon they will stop mining and go to another business. In the Luc Yen district as we visited the region during spring 2010, local people perform most of the gem mining. When they are not busy with other activities like farming or social events, they have the choice between staying at home doing nothing, going to mine gems, going to cut wood in the forest or to go poaching. Many people in Luc Yen seems to prefer gem mining as it provides them some additional income and mining for gems they hope to get lucky and feel that they have a chance to get find a good stone that will change their life for the best. They know that farming rice they will never get rich, On the other side if gem mining is hard job, they feel that they also have a chance to change their life.


Hope and hard work are the two realities of gem mining. If hope can nevertheless be a cruel mistress or a short-cut to deception, nevertheless it give them a reason to live, to wake up in the morning and do something with their time that will be useful for them and their families... And funnily this gem fever is commonly very contagious for young gemologists as arriving in Yen The everybody was ready to go for long days walking in the misty mountains, on dangerous slippery tracks.


The first day of our expedition the weather was misty and we started walking under a gentle rain. It was not too hot, but the expedition was challenging as the way to the mines was then very muddy and the numerous marble pinnacles were very slippery. We had to be very careful particularly while passing over the numerous deep crevasses using some slippery (and scary) wood "bridges". After a little bit more than two hours walking we reached the Bai Gau blue and pink spinel mining area to find out that, due to the rain, most of the miners were not working that day but instead were resting eating red rice and drinking rice alcohol. The following days the weather was sunnier and thus walking was safer in these mountains as the muddy jungle paths and the rocks were becoming less slippery. That was good as day after day if the spirit of the author's team was still very high, our bodies were starting to feel tired.

Each day reaching the gem mining site after several hours of hard walk, meeting the miners, looking at their production and sharing some of their time was a wonderful experience for the young gemologists in the author team... Most of them surprised themselves in these mountains: Each evening we were all very tired but our memories were full of beautiful natural landscapes, gems and encounters with gem people. For the author who used to be a hunter in countryside France, there was no surprise: It was just the feeling and the taste of the real thing. For the young passionate gemologists like those I took with me on that expedition to Vietnam, as it was the case for the author when he decided to come in Burma and Thailand to study gemology, there is just nothing like going to the mines...

The author would like to thanks all his travel companions for their courage and their enthusiasm. It had been a real pleasure to travel and work with them in Vietnam. Thanks to their support we have been able to add many interesting specimens to the GIA Reference Collection. We would like also to thanks all the people (miners, gem merchants, farmers...) we met in the Luc Yen district for their welcome. It has been a real pleasure to share with them some instants in the mountains of the Luc Yen district. In Vietnam if we found few nice gems we truly met many gemmy people!

 

The author would like now to invite you to visit the Vietnam 2010 Luc Yen Expedition photo gallery, you will be able to enjoy the beauty of one of the most beautiful gem mining area in South East Asia.. (AVAILABLE VERY SOON...)

 

All the best,

Blog Title: FE08: Vietnam: A visit to gem mines between the sea and the sky.


GIA FE08 (GIA Laboratory Bangkok Field Expedition 08): May. 15 - Jun. 10, 2009: Vietnam
After our FE02 expedition to Vietnam in Jan 2009, we had now all the contacts and were able to make all the arrangements in order to be able to conduct a complete survey of Vietnam mining areas. This project was done in collaboration with:
- Dr. Pham Van Long, a well known Vietnamese geologist and gemologist working as Director of the "VGC Center for Gem and Gold Research and Identification" in Hanoi. This is the Vietnamese official gemological laboratory which also delivers all the necessary paperwork to export legally gemstones from Vietnam.
- Mr. Hoc, my old friend, a local French speaking Vietnamese tour guide working for Viet-Y. I was working with Hoc while visiting Vietnam during the 1990's when I was working as a tour guide in Vietnam for FRAM, a major French Tour Operator.
To help me in this expedition were several friends, all experienced travelers: Jean Baptiste Senoble (from France, in charge of photography and sourcing), Kham Vannaxay (from France, video and translation as he speaks Vietnamese), David Bright (from USA, in charge of GPS recording and photography) and Lou Pierre Bryl (Canada, in charge of photography and accounting). Note: as usual, all the team members were financing their own traveling costs and their part of the common costs in this join expedition.
Our program was to visit first the ruby and spinel mining areas in North Vietnam in the Yen Bai and Nghe An provinces and also a pearl farming operation in Ha Long Bay and an experimental farm in Hanoi. Then we were planning to visit the blue sapphire deposits in the south of the country located in the Highlands region north of Saigon (Ho Chi Minh City).

After a short stay in Hanoi to arrange all the expedition details, the first part of our expedition for the GIA Laboratory Bangkok was to visit the Yen Bai area with the Tan Huong and Thac Ba Lake ruby and spinel mining areas. Sadly due to the heavy rains of the previous week all mining stopped as the water level was high. We then left to Truc Lau (ruby and spinel) and then Yen The, the main city of the famous Luc Yen district of the Yen Bai province. If our first day in Yen The was rainy and thus spent to visit the local gem market and the different town dealers, the following days were blessed by a sunny weather which enable us to visit all the mining areas we planned to visit. That was wonderful as the author was not able to visit them as he wanted in 2005 and Jan. 2009 due to the weather conditions: We first visited on May 19th the Bai Chuoi and Khoan Thong mining areas which were the places were the Thais and VIGECO were mining with machinery during the 1990's. Then on May 20's we moved to the An Phu area to visit the Cung Truoi 2 and 3 (Note: "Cung Truoi" means "the Sky Gate" it is a high marble cliff which is divided in three areas: Cung Truoi 1, 2 and 3) ruby and spinel mining areas in a failed attempt to visit the May Thuong ruby mining area (Note: "May Thuong" means "the high clouds" as this is one of Vietnam most remote and difficult to access ruby mines). The expedition was very difficult due to the jungle covered karst type terrain where we had literally to jump from marble pinnacle to marble pinnacle risking at each step a serious wound if we put our feets in the wrong place. The following day, using a different guide and path we visited the Cung Truoi 1 red spinel mining area and finally, after another very hard walk in the karst type cliff, we succeeded to visit the May Thuong ruby mining area which is producing most of the ruby in matrix specimens seen in Luc Yen region markets. Then on May 22, we went on the track of Vietnam fabulous blue spinels and were able to visit the main deposits in Bai Son and Co Ngan after another hard walking day in the jungle covered mountains. After these great four days hiking Luc Yen region scenic but deadly mountains we returned to Hanoi exhausted but really happy...

Back in Hanoi we got prepared for the second part of our expedition which was about pearls: We first visited a cultured pearl farm producing "akoya" type pearls from "pinctada fucata" oysters on Ha Long bay and its hatchery located nearby. The visit was interesting as we could witness on the Bay the grafting process. Later in Hanoi we could visit a experimental fresh water bead nucleated pearl farm producing pearls from mussels.

We then visited in Hanoi a melo pearl dealer and were able to get some interesting useful information that enabled us few days after to visit the Cat Ba island and its port and to meet there Vietnamese melo melo fishermen. We were able to study several specimens of these mysterious sea snails producing in very rare cases one of the rarest, largest but also one of the most beautiful natural pearls: Melo pearls. (Read our report on www.giathai.net: "Melos and their pearls in Vietnam" for more details)

Finally after a visit to the Quy Chau and Quy hop ruby and sapphire mining area, which was very quiet, we took the plane to Saigon (Ho Chi Minh City) in order to visit the blue sapphire deposit of Vietnam Highlands. We started our survey on the cost around Phan Thiet city with the deposits near Da Ban and with Ma Lam villages. Then we took the road to the mountain to visit the former mining area near Di Linh where there is currently no activity as most of the local working force is busy working in the coffee plantations which have replaced all the jungle and covering nowadays all the region. We finally left to the new province of Dak Nong (formerly Gia Nghia) where we scouted the Dak Ton and Dak Rung mining areas. There as the coffee was not yet replacing all the jungle we could find after several hours walking in the jungle some small scale mining areas and meet some sapphire and zircon miners.

They after this visit to the south we returned to Hanoi in order to do, with the help of Pham Van Long, the necessary paper work for the export of our samples and returned to Bangkok on June 10th after a truly very successful field expedition.

All the best,

Blog Title: GIA FE02: Vietnam: Rubies, spinel and pearls from the north.


GIA FE02 (GIA Laboratory Bangkok Field Expedition 02): Jan. 03- Jan. 13, 2009: A visit to North Vietnam!
For my second field expedition for GIA, as our focus was on that first winter and spring season on ruby and sapphires from South East Asia, I decided to scout again Vietnam. The last time I visited Vietnam gem mining areas was in 2005 and in order to prepare a full scale expedition scheduled for May and June 2009, I decided to take advantage of the fact that one of my friends from Switzerland was visiting the area. Sadly, just few days before the beginning of the expedition, he told me that he would not be able to join it.
With the support of Vietnamese gemologist Pham Van Long, and with my old friend Hoc, I was able to visit again the Yen Bai and Luc Yen ruby and spinel mining areas for 5 days: As most people in Vietnam were preparing the "Tet": The Vietnamese New Year, mining was quite low. Nevertheless we were able to visit the spinel mines on a marble cliff near An Phu village and several alluvial type mines in the rice fields around An Phu and Minh Tien villages:

It was also very interesting to meet people in Yen The city, the local gem trading center of the Luc Yen province. There we could see that in less than 20 years the gem mining and trading industry has turned into something very successful: Besides high quality rubies and spinels which will finish on international gem markets, we saw a very busy industry turned to the local Vietnamese market producing gemstone paintings and carving: A great way to use the gems too small or those which quality is not good enough to be used on jewelry... Thanks to these paintings and carvings, the local miners can find a market for their production and thus get some regular income even the day they are not lucky to get a fine stone. Thanks to that they are mining day after day and thus the conditions for fine gems (like the following star ruby) to be find are present!

After that visit to the gem mines in the mountains of North Vietnam, I returned to Hanoi where I was joined few good friends to continue our expedition with a week end on the famous Ha Long Bay in order to visit a pearl farm producing Akoya type cultured pearls and rest a little.

This second Field Expedition for GIA was again a success! It was also very nice to see again all my Vietnamese friends and to travel again in this beautiful country.
All the best,

Blog Title: Vietnam 2005


A visit to gem markets and gem mining areas in North Vietnam (Spring 2005):

Abstract of the Vietnam 2005 page (Available at that link): This web page presents the field expedition lead by Vincent Pardieu (then Director of the AIGS Gemological Laboratory, Bangkok, Thailand) to North Vietnam. This fieldtrip was part of the expedition supported by AIGS and Gubelin Gem Lab with the help of ICA to Asia and Africa during summer 2005. During that expedition the author was helped by Jean baptiste Senoble, a young French gemologist who was the author student at AIGS Bangkok in 2005.



During that expedition, Hanoi was our main base. We started our visit traveling to the ruby, sapphire and spinel deposits located near Yen Bai and in the Luc Yen district. We continued our expedition visiting the Ha Long Bay where we found some interesting pearl farms. Finally we went south of Hanoi near Vinh in the Nghe An Province in order to visit the Quy Chau ruby mining area.
