Certificates of Quality

Each of our stones has its own individual certificate (just like a birth certificate), which accompanies the diamond throughout its lifetime. Every diamond has a unique number laser-engraved on its edge, which matches the number shown on the certificate.

Inbar offer only the most esteemed certificates. These are primarily from the Gemological Institute of America (GIA), whose ranking system is the most prestigious in the world, evaluating the color of the diamond, its purity, the quality of the cut, its proportions and symmetry. In European markets, we use only the famed Belgian HRD certificates. Together, these are the Rolls-Royce and Bentley of precious stone testimonials, so we recommend that customers adhere to them.

International certificates are provided for stones of 0.30 ct. or more. However, INBAR Diamond Center has long been collaborating with a certified gemologist, and with its professional guarantee, it issues its own professional certificates to clients and owners of small stones.
