What is a Certificate?

A certificate is a "blueprint" of a loose diamond. Also called the diamond grading report or diamond dossier, it tells you the diamond's exact measurements and weight, as well as the details of its cut and quality. It precisely points out all the individual characteristics of the stone. Certificates also serve as proof of the diamond's identity and value.

A certificate is not the same thing as an appraisal. A certificate describes the quality of a diamond, but it does not place a monetary value on the gem. All Mondera Loose Diamonds featured in our Diamond Store are graded by the GIA or AGS laboratory.

Who Issues Certificates?

There are many diamond labs that issue certificates, but the Gemological Institute of America (GIA) and the American Gem Society (AGS) are the two most widely regarded and recognized diamond grading labs in the world. All Mondera Loose Diamonds featured in our Diamond Store are graded by the GIA or AGS laboratory

There are many diamond grading labs in operation, many of which produce their own grading reports. Different labs have different grading standards, and some labs will be more lenient with their standards than others.

Why Do I Need a Certificate?

Shopping for graded loose diamonds allows you to make an informed choice about your selections, and to comparison shop. You can compare one diamond with a particular weight and quality with other loose diamonds of similar weight and quality to determine which has the better value.
