Diamond Certification

Diamond Certificates

A certificate is a "BluePrint" of a diamond, it tells you the diamond's exact measurements and weight, as well as the details of its cut and quality.

A diamond certificate, also called a Diamond Grading Report, Diamond Dossier or Diamond Quality Documnet, is a report created by a team of gemologists.

It gives you a detailed scientific analysis of your diamond which is done by an impartial gemological institution, not the grading of the seller.

The diamond is evaluated, measured, and scrutinized using trained eyes, a jeweler’s loupe, a microscope, and other industry tools.

Diamond appraisals tie up any loose ends in a diamond purchase, confirming still that the characteristics of the purchased diamond match not only the description given by the seller but also the description on the diamond certificate.

It precisely points out all the individual characteristics of the stone.

It also serve as proof of the diamond's identity and value.

A certificate describes the quality of a diamond, but it does not place a monetary value on the gem.

A diamond certificate or grading report provides an expert opinion on the quality of the diamond and is provided by an independent gemology lab.

A completed certificate includes an analysis of the diamond’s dimensions, clarity, color, polish, symmetry, and other characteristics.
