Analyze, test, and certificate
A diamond certificate, also known as a diamond grading report, is an easily understood document prepared by an expert gemologist that describes the key characteristics of a diamond. A certificate from a gemological laboratory verifies the quality of a loose diamond and allows non-experts to make educated diamond buying decisions. We rely on 4 highly regarded, internationally acclaimed gemological laboratories to certify every loose diamond we offer. These laboratories use universally recognized standards for grading diamonds.
