THE FRENCH LABORATORY OF GEMMOLOGY

This laboratory’s mission is to expertly examine the gemstones submitted to it. Without this scientific approach, it would be impossible to delve into the heart of the material and thus determine its composition with certainty. The certificate obtained (the gem’s identity card) guarantees and protects the consumer.

Meeting with Olivier Segura, its director

What do you like about your job?

The contact with the stones, with the pearls.
The possibility of getting to know their composition better, to delve into their chemistry.
It is also thanks to the French Gemmology Laboratory that I can have very different clients, ranging from jewelers to artisans, as well as multinational companies.
My job means that our relationships are very cordial; it’s an exchange; I’m passing on knowledge.
That is why I created the gemology school, to share this knowledge.
