The French Gemmological Laboratory (LFG)

The Paris gemmology laboratory

The French Gemological Laboratory is the leading gemmology laboratory in France. It is the world's oldest laboratory still in operation. Founded in 1929 by the Chambre Syndicale du Diamant, it has been part of Union BJOP (the French Union of Jewellery, Goldsmiths, Stones and Pearls) since 2011.

LFG offers analysis of gems, diamonds, pearls and colored stones. ISO 9001 certified and RJC (Responsible Jewellery Council), it is renowned for the quality of its analyses. Indeed, it is the only laboratory in France to offer scientifically-based analyses. During the gem analysis process, numerous experts are involved to guarantee the objectivity and reliability of the analysis report. Gem analysis results in an internationally recognized authenticity report, as well as an identification report. The LFG publishes over 5,000 analysis reports every year!

As the world's oldest gemmological laboratory, the LFG boasts an impressive gem library, enabling it to further enhance the reliability of its analyses, as well as state-of-the-art equipment and techniques.
