Diamond Grading & Certification

Diamond grading reports, often referred to as a diamond certificate, is a formal, scientifically-based assessment of a diamond, based on the shape and features that are individual to it. The Faltz Diamonds & Jewelry group work with a number of widely recognized entities that provide diamond grading reports according to a quality grading system known as the "4 Cs" - Clarity, Cut, Carat and Color. Every report informs us of the authenticity of the diamond, as well as its proportions and finish.

Diamonds should only change hands when accompanied by a certificate/ report attesting to quality. The diamond certificate will provide our diamond appraiser with information about the diamond's qualities and features, which will assist in determining the value of the stone in current market conditions. Our appraiser will also conduct an independent, comprehensive evaluation of the diamond's background, its origin, its legitimacy and the accuracy of its certificate.

At this stage, as in every stage throughout the process, we will support your independent authentication process should you wish to conduct one in parallel.

We work with a range of leading diamond certifiers worldwide, to meet a variation of customer needs:
