Each jewellery piece with precious stones has always a certificate of authenticity for these stones.

Diamonds weighing over 0.50 ct addition have an international certificate of one of the world's leading gemmological laboratories (HRD, GIA or IGI). (Due to the long duration and high cost of the procedures necessary for the analysis of stones, these certificates are used for diamonds of greater value.)

We guarantee that the stones used to manufacture our jewellery meet highest standards of the United Nations and are conflict free.
