What the Names of Stones Say About Us

Since November 2021, the Gemmologie et Francophonie association has been offering round tables at the GemGenève
fair on current topics related to gemology. Also, the last edition of the GemGenève show, which took place from November
3 to 6, 2022, was no exception to this rule and the association had the pleasure of hosting a round table around gems
nomenclature in both science and trade.

In this article, we offer a summary of the main topics covered by selected specialists:
gem nomenclature and its importance in gem reports produced by laboratories. If mineral nomenclature is well established
by the scientific International Mineralogical Association, gem nomenclature follows trade names that are sometimes left to
interpretation. The experts clarified these different aspects and raised important issues regarding practices in gem labs and
use in the gem market – and tried to propose answers.
