Conferences & workshops


Corporate meetings, cultural centers, circles of friends, assisted living centers, clubs, associations…would you like to put on a conference on an original theme as educational as it is fun?

COM’GEM offers conferences on gemstones and jewelry.

The presentation and explanation of gemology naturally introduces the many types of stones. Whether they are precious, semi-precious or decorative, their principal characteristics and their use in jewelry are described. The different professions within the domain of gemology/jewelry and the tools used in the identification of these gemstones are also presented.

In Paris South (at the foot of the metro), these activities are given by Catherine Aubert, gemologist, author of “Dina à la loupe, une vie de passion pour les pierres précieuses” and the “Jeu des 7 parures” cards game.

Practical details (date, cost, place, public, logistics) on request.
