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.

Special THANKS for their support for our field expeditions since 2005:
about gems, gemology, field expeditions, studying gemology, minerals, jade, pearls or jewelry? We recommend these FORUMS where the author is contributing:
Do you want to STUDY GEMOLOGY?
Here are some recommended institutes where the author studied gemology in Thailand ... and was happy about his investment!
For those willing to go further after their gemological studies: Recommended Advanced Gemological Courses:
To finish here are some BOOKS about gemology the author have read and appreciated and would like to recommend to people willing to learn more about gemstones, gemology and the places where gemstones are found:
A visit to Tsavo ruby and tsavorite mining areas, Kenya (October 2007):
The following "Gemstone mines of Kenya" web pages presents the result of the two gemological expeditions to East Africa in Jul. and Aug. 2005 and Oct. 2007.
The July and August 2005 expedition was a join expedition financed by the AIGS gemological Laboratory in Bangkok, Thailand (where the author was then the Laboratory Director), the Gubelin Gem Lab, in Lucerne Switzerland and Jean Baptiste Senoble, a young gemologist who was interested, after completing his gemological studies at the AIGS, to discover where the gems which were fascinating him where coming from. It was possible thanks to the support of the ICA (International Colored stone Association).
The Oct 2007 expedition was also part of a larger expedition to East Africa initiated by Richard W. Hughes, the author of "Ruby and Sapphire". The author was then gemologist at the Gubelin Gem Lab. Two young gemologists: Guillaume Soubiraa and Michael Rogers, and one of Guillaume friends: Philippe Brunot joined us in this expedition to Kenya.
The purpose of these expeditions was to visit ruby, sapphire, alexandrite, emerald, tsavorite, tanzanite and tourmaline mines in Kenya and Tanzania for gemological research purpose. Origin determination of gemstones like rubies and sapphires is the passion and an important part of the work I had to do while working in gemological labs like AIGS, Gubelin or later GIA. It is then important for a gemologist willing to specialized himself in the origin determination of gemstones to collect data on gems not only studying the reference collection inside the gem lab but also directly at the source. As a former tour guide, turned into a gemologist, it is my pleasure to share the benefit of these expeditions with you and I hope that it will benefit to the people who welcomed and helped us in the field.
