The oldest gemmological laboratory in the world, the French Gemmology Laboratory was founded in 1929 by the Diamond Trade Union Chamber.
Attached to Union BJOP in 2011, the LFG continues to serve its mission of providing independent expertise in gems for consumer information and safety.
Now located in the very heart of Paris, in the 2nd arrondissement, the LFG is the only laboratory in France to offer analytical reports on all gems, diamonds, coloured stones, and pearls, with regard to dimension, characteristics, identity, form and colour.
The Laboratory’s reports are distinctive in that all conclusions are based on science and are not mere opinions, thus giving real added value to the certification.
– Gem identification
– Authenticity of their nature, colour, detection of any treatment
– Identification of imitations and syntheses
– Diamond Graduation (4C)
– Authentication of pearls
– Specific study on request (nature of inclusion, determination of type of deposit, etc.)
– In-depth research in collaboration with universities providing high-level technological support
Our added value compared to other Laboratories is that we rely on published scientific works. Our internal procedures are built by the scientific community. We thus offer a secured service.
