We draw your attention to security measures related to the purchase of a precious stone. A number of dishonest merchants deliver stones that do not correspond to the certificates that accompany them.

If you are considering investing in a diamond, you require two guarantees on the part of any merchant : a laser-engraved certificate number (in the case of a diamond), as well as laboratory sealing of the stone (for all stones). The latter condition will enable you to detect a fraud without any possible doubt.

Laser engraving is not to be overlooked. Once the stone is mounted in a piece of jewellery, you will be able to recognise your gem thanks to this engraving by using a simple magnifying glass (there is no need for a microscope). The certificate number must be preceded by the company logo of the laboratory that performed the appraisal, and of course, the certificate should mention the engraving.
