The certificate

The Maison provides a unique, numbered certificate of authenticity for each creation that authenticates the origin of your jewel.

Diamonds over 0.20 carats also come with a certificate delivered by gemological laboratories such as the GIA (Gemological Institute of America). This certificate is the diamond’s identity card: it authenticates the stone’s characteristics, such as its weight, cut and origin.

Although both certificates must be stored carefully, please note that the second one is unique: neither the Maison nor the GIA keep copies of it.
