Before purchasing a diamond, you should expect to reiew a copy of its certificate as proof that it has undergone an unbiased professional examination.
A diamond certificate, also called a diamond grading report
, diamond dossier®
, or diamond quality document
, is a report created by a team of gemmologists. The diamond is evaluated, measured, and scrutinized using trained eyes, a jeweler’s loupe, a microscope, and other industry tools. A completed certificate includes an analysis of the diamond’s dimensions, clarity, colour, polish, symmetry, and other characteristics. Many round diamonds will also include a cut grade on the report.
