When identifying the melee, LLG determines precisely whether the diamonds are natural, synthetic or processed. Obtaining a certificate from a serious laboratory therefore assures you of the exact nature of your gems. This is particularly important since the strong development of synthetic stones in the gemstone market.
Save time and gain more precision
LLG offers for professionals a rapid identification service of their diamond melees to determine whether their stones are natural, synthetic or treated.
Thanks to the expertise of our team and the advanced technology of our equipment, our laboratory is able to carry out this service.
Indeed, all members of our team are university graduates or scientific researchers trained in the best gemmology institutes.
LLG therefore uses, amongst other instruments, the AMS2 which is the latest measuring instrument created by De Beers. The precision of this instrument allows us to sort though diamonds ranging from sizes 0,0033 points (0,99 mm diameter) to 20 points.
