List of authenticity reports

On this page you will find various authenticity reports, free to download.

These reports are issued by the LFG from Paris following analysis of certain stone samples we regularly entrust to them.

LGF is the French gemmology laboratory in Paris. It was founded and operates in accordance with the national charter of expertise and the recommendations of the French Ministry of Higher Education and Research. The laboratory is independent.

When we receive a new shipment of minerals, we select one or more samples from a batch and submit them to LGF for analysis. We have adopted this working method to ensure maximum security as to the quality and authenticity of our stones. We would like to point out that, given the cost of analysis, it is obviously impossible to have every stone or pearl sold appraised. However, this method of appraisal enables us to carry out regular checks, thereby ensuring the sincerity of our suppliers and the confidence of our customers.

La pierre a été polie soit à l’huile ou avec de la résine afin de résorber les possibles micros-fissures de surface. C’est la raison pour laquelle il y a des résidus trouvés sur la pierre. Ceci n’altère en rien la naturalité ainsi que la qualité du produit. C’est une technique utilisée en bijouterie pour ce type de pierre.
