The certificate of authenticity of a stone is the guarantee of its qualities by a certified laboratory.

We take great interest in the quality of our gems during our purchases. The certificates we produce come from gemological laboratories in the country of origin, or from a French laboratory if applicable.
Given the new treatments existing on the precious stones market, in-depth analyzes are necessary to validate our observations in the field, observations limited by the equipment on board during our surveys. The quality of the stones purchased is thus guaranteed in complete safety and transparency.
We work in particular with the following independent laboratories: Laboratoire Français de Gemmologie (LFG - Paris), Precious Gem Testing Laboratories (PGTL - Sri Lanka), Ceylon Gem Laboratory (CGL), Emteem Gem Laboratory (EGL - Sri Lanka), CDTECH (Colombia) ),
If one of our stones is offered without a certificate, the request can be made at the official price from the French Gemmology Laboratory, with approximately 3 weeks of waiting. The cost will also vary depending on the weight and nature of the stone.
Our team is ready to answer all your questions by email, phone or post.
