As a certified gemologist, Valérie Danenberg only sells GIA certified diamonds (the only worldwide acknowledged laboratory). All our diamonds are laser engraved on the girdle with their GIA certificate number.
All of our brilliant cut diamonds weighing over 0,30 carat come with their GIA certificate. Over 0,40 carat, oval-shaped diamonds and all the other fancy shapes come with their GIA certificates as well. Each jewel comes with an additional certificate that authentifies its metal and precious stones.
Certificats of authenticity
A certificate attesting to the authenticity of the metal and precious stones making up each piece of jewelry is issued with every purchase of a Valérie Danenberg creation.
