Rhodonite Certificate of Authenticity

What is the French Gemmology Laboratory?

The Laboratoire français de gemmologie (LFG) is the oldest gemmology laboratory in the world. Founded in 1929 by the Chambre syndicale du diamant (Diamond Trade Association), it has been part of the Union BJOP (French Union of Jewellery, Gold, Silversmiths, Stones and Pearls) since 2011. Its main mission is to authenticate gemstones to inform consumers.

The Laboratoire français de gemmologie prides itself on ensuring that every report it produces is based on rigorous scientific analysis. It is, in fact, the only laboratory in France to offer scientifically-based analyses for diamonds, gemstones, coloured stones and pearls. The certifications issued by the LFG are recognised worldwide for their reliability and security, which is why major jewellery houses, such as Cartier, Van Cleef & Arpels, Chaumet and Boucheron, trust it to guarantee the authenticity and quality of their precious stones.

Founded and operating according to the National Charter of Expertise, the LFG also complies with the recommendations of the Ministry of Higher Education and Research. This laboratory is entirely independent, thus guaranteeing the objectivity and neutrality of its expertises.

This approach allows us to best guarantee the quality and authenticity of our stones. Although systematic analysis of every stone or pearl is impossible due to high costs, this regular expertise protocol constitutes a reliable control. It contributes to strengthening transparency with our suppliers and maintaining the trust of our customers.
