Why is ethical sourcing important in a modern society?
It’s important for us because we are working in a sector based on ethical and confidence traditions. We don’t want our industry to be used for fear of violence and country’s instability. To show our commitment, we are RJC certified.

Why informing customers that their purchase conforms to ethical standards has become a necessity?
The origin of the materials is something important because the new generations want to know what they are buying in terms of ethics and sourcing. In our case, we are a services company so we don’t buy or sell materials.

What is your background?
I learned geology and gemology at the university of Nantes (France). I started to work at the Frenchgemmological laboratory in 2006 and after 2 years at the national institute of gemmology, I come back to the lab in 2011 as manager of the diamond department and since 2018, I am the director of the French gemological laboratory, the oldest lab, created in 1929.
The aim of the French Gemmological Laboratory is to analyze gemstones (coloured stones, diamonds and pearls). We are working with everyone, high jewellery brands, traders, auction houses or individuals.We have services for melees diamonds for identification and grading. We do grading reports for loose diamonds. We can determine the nature of all gemstones, their treatments and the geographical origin.

How would you describe the last ten years?
Our desire has always been to make the most scientific and precise analyzes possible. So we are ISO 9001 certified and under ISO 17025 accreditation. The reputation of the LFG has been growing since 2010 and our reports are more and more requested. We want to promote again our lab. with an exponential growth in sales and a very consistent range of clients who purchase on a regular basis and a vast growth in new company registrations.
