Chopard entrusts its diamonds to two independent laboratories: the Gemological Institute of America (GIA) and the Hoge Raad voor Diamant (HRD). To receive its numbered certificate, each stone is studied by several gemmologists who verify the diamond’s authenticity and evaluate all the stone’s characteristics in a non-biased manner. In addition, each Chopard piece of jewellery also comes with a certificate of origin guaranteeing the piece is a genuine Chopard original.

As a certified member of the RJC, the Maison supports the Kimberley Process and the World Diamond Council, two organisations working to eliminate all trade of conflict-zone diamonds. To actively support them, Chopard has put a system of self-regulation into place for all its suppliers, requesting they not buy or sell conflict diamonds and encouraging them not to purchase stones from unknown sources. In this way, each jewellery creation from the Chopard workshops comes with a certificate guaranteeing its origin.
