A diamond certificate, also called a diamond grading report, is a report created by a team of gemmologists. The diamond is evaluated, measured, and scrutinised using a variety of spealised equipment. 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. Independent diamond certification is essential for authenticity and also insurance purposes. It can be considered as verification by an independent company with no conflict of interest between buyer and seller. Diamond certifications are issued by independent gemological laboratories.
