Diamond Guarantee

At Joaillerie Royale, all our diamonds are certified and provided with a certificate in due form based on the criteria of the largest laboratories (HRD, GIA, IGI). We guarantee the absolute quality of our jewellery. The certificate is recognised worldwide and internationally. 

The certificate gives all the important information about the stone: its characteristics (carat weight, colour, purity and cut), its proportions and the quality of its cut.

You have a 10-year guarantee on all our set jewellery. Always keep the certificate as it is the identity card of the jewel.

Almost all our diamonds are certified by internationally renowned laboratories that are recognised by our profession.  Polishing, cleaning, verification of the setting is possible on the jewel as well as an engraving. 

We are responsible for all manufacturing defects of the jewel and the diamond but we do not cover accidental shocks.
