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.

A visit to gem markets and gem mining areas in Madagascar (Autumn 2005):
Abstract of the Madagascar Autumn 2005 expedition: For that expedition the author was asked by Richard Hughes and his friend Dana Schorr if he could take him to visit the sapphire deposit in Ilakaka and the ruby deposit in Andilamena the author recenrly visited in June 2005. That expedition was the first time the author was traveling in the field with Richard W. Hughes. It was a great occasion for the author to spend some time with the author of "Ruby and Sapphire" the book that was largely responsible for the author decision to move from his past tour guide career into a becoming a gemologist.
That expedition was planned with the support of Tom Cushman, Danile Grondin and Marc Noveraz. We started our visit traveling from Antananarivo to Ilakaka where we visited the sapphire mine run by Marc Noveraz at Ampasimamitaka. That visit was an important one as later the analysis of the sapphires collected there revealed that some of these blue sapphires were containing naturally significant levels of beryllium, an element that was so far only believed to be present in beryllium treated stones. After visiting the Ilakaka and Sakaraha sapphire mining area we returned to Antananarivo and took the road to Andilamena. There we visited the Andrebabe sapphire deposit and the ruby deposit located in the jungle East of Andilamena.

After that expedition a report was published by Richard Hughes on his website: "Sorcerers and sapphires, a visit to Madagascar" on www.ruby-sapphire.com. On his side the author published two short articles for InColor, the ICA Magazine, and the "Revue Francaise de Gemmologie AFG" about the discovery of sapphires containing naturally beryllium:
A visit to gem markets and gem mining areas in Madagascar (Summer 2005):
Abstract of the Madagascar 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 Madagascar in May 2005. 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 and Tanguy Lagache, two young French gemologists who studied gemology at AIGS in Bangkok in 2005.
That expedition was planned with the support of Daniel Grondin and Marc Noveraz, two european gem merchants based in Madagascar. We started our visit traveling from Antananarivo to Ambohimandroso a ruby mining area located near Ansirabe. Then we continued to the sapphire mining area around Ilakaka and Sakaraha where Marc Noveraz was based. We then travelled by land to Andranondambo, the area where sapphires were first discovered in Madagascar. We returned then to Antananarivo to travel to the ruby mining areas near Vatomandry and Andilamena. Finally we visited the Anbondromifehy sapphire deposit located in the north of the country.
"A miner's vision of the world" After that photo, taken by Tanguy Lagache in 2005 from the deep of a sapphire mining pit in Andranondambo, the author will continue collecting such photos from the deep of a gem mining pit. Photo: Tanguy Lagache, 2005
After that expedition the author worked on a serie of three articles in collaboration with Richard Wise for Colored Stone Magazine. These articles are visible online on Richard Wise website:
