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.

The 2005 and 2007 expeditions were supported by the Gubelin Gem Lab located in Luzern, Switzerland, as the 2005 expedition was financed by the Gubelin Gem Lab and the AIGS Gemological Laboratory in Bangkok, Thailand and, because at the time of the 2007 expedition the author was working at the Gubelin Gem Lab as a gemologist.
The Baraka Tsavorite mining operation, Mindi area, Taita Hills, Kenya:
The mine located not very far from the Bridges Scorpion mine is run by Elizabeth, a Kenyan lady with a lot of experienced in tsavorite trading. When we visited the mine in 2005 and 2007 it was mainly composed of a large open pit located at (03°46'27"S 38°25'41"E) where about 10 to 20 miners where working with jackhammers under the supervision of Elizabeth in 2005 and her 23 years old daughter Wangui Gladwell in 2007. After visiting the mine in 2005, Elizabeth and her brother Geoffrey Karuiki recieved us in their mining camp located near the open pit mine where we could see some tsavorite pockets. In 2005, Geoffrey Karuiki took us for a walk in the bush in order to visit an area where they were doing prospection trenches. In the trenches we visited no tsavorite was found but rubies and green chrome tourmaline were present as seen on the following photos.

Notes about the Kenya gemstone mines pages (Edited on Oct 10, 2008)
These "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. They were build with the support of ICA (The International Colored Stone Association) and particularly of ICA ambassador to Kenya Suzie Kennedy and her husband Kennedy Khamwati for the Kenya part. Kennedy was nice enough in 2005 to take us to visit all the ruby and tsavorite mines we wanted to visit. His help, presence and permanent support was highly appreciated. In Oct 2007 we were helped in the field by ruby and tsavorite miner and ICA member Genson Micheni Musa, the owner of the Tsavolite mine near Tsavo. Micheni support was also very much appreciated. I want here to dedicate these pages to Kennedy and Micheni as without them I would not have been able to collect and share all these notes about gem mining in Kenya.
The Jul. and Aug. 2005 expedition was a join expedition by the AIGS gemological Laboratory in Bangkok, Thailand (where I was then the Laboratory Director) and the Gubelin Gem Lab, in Lucerne Switzerland. I was then traveling with Jean Baptiste Senoble, one of my former AIGS gemology student, working as I write these words in 2008 for Nomad's Co Ltd, a Bangkok based gem dealer.
The Oct 2007 expedition was also part of a larger expedition to East Africa I lead in collaboration with gemologist Richard W. Hughes. I was then gemologist for the Gubelin Gem Lab. Two young gemologist and former AIGS students: Guillaume Soubiraa and Michael Rogers joined me in this expedition as well as One of Guillaume Soubiraa friends from Madagascar: Philippe Brunot.
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 an important part of the daily work at the Gubelin Gem Lab and it is important for a gemologist specialized in origin determination of gemstones to collect data directly at the source in order keep his knowledge of the world gemstone mining areas updated. 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.
Please visit the other Kenya pages on fieldgemology.org:
Special thanks, to all the Kenyan authorities we met which provided us support and help, to the miners who welcomed us at their mines, shared with us their time and their life. Your support and welcome was much appreciated! I hope that this report will be useful to all people we met in Kenya and to all the people interested in the gem trade from the production areas in Kenya to the consuming markets and for all gem lovers around the world.
Now I would like to give a more personal thanks to the following people as without their help and support during these expeditions to Kenyia, I would not have succeded in these expeditions:
First thanks to my traveling companions which helped to finance, to organize and to make this expedition a succes:
Jean Baptiste Senoble currently working for the Nomad's company in Bangkok was my gemology student at the AIGS, in Bangkok and became then one of my regular traveling companions to gem markets and mines around Bangkok. He was my traveling assistant during the 2005 gemological expeditions to Vietnam, Sri Lanka, Madagascar, Kenya and Tanzania. We returned together in Tanzania and Madagascar in 2008. Without his help and support these expeditions would not have even been possible. All the best to you JB!
Guillaume Soubiraa (from SMDA in Madagascar) and Mike Rogers, two former students of the AIGS in Bangkok and Philippe Brunot, one of Guillaume childhood friends from Madagascar were my travelling companions while visiting Kenyan ruby and tsavorite mining areas in October 2008. Thanks to their presence, support and presence this expedition turned to be a pleasure and a success.
All the best guys and great thanks!
These 2005 and 2007 expeditions to Kenya tsavorite and ruby mines would not have been possible without the help of local members of the Kenyan gem trade:
Suzie Kennedy is the current ICA Embassador to Kenya. With her husband Kennedy Khamwathi, they are some very active members of the Kenyan gem trade. Our 2005 and 2007 expeditions were possible thanks to their help and support.
The presence of Kennedy each day during all our 2005 expedition was very much appreciated and so useful to the succes of this expeditions. Really thanks to both of you!
Genson Micheni Musa is a Kenyan ruby dealer which turned into a tsavorite miner in Kasigau area. His mining company "Tsavolite" is located just near the famous Tsavo National Park. Micheni was a wonderful and friendly guide during our October 2007 expedition. His knowledge of the Kenyan gem trade and of the Tsavo area was very useful to the success of our expedition. Thanks Micheni!
The 2005 and 2007 expeditions were supported by the Gubelin Gem Lab located in Luzern, Switzerland, as the 2005 expedition was financed by the Gubelin Gem Lab and the AIGS Gemological Laboratory (Bangkok, Thailand) and, because at the time of the 2007 expedition the author was working at the Gubelin Gem Lab as a gemologist.
