What is a Certificate?
A diamond certificate, also called a diamond grading report, is a report created by a team of gemologists and provided by an independent gemology lab. The diamond is evaluated, measured, and inspected using trained eyes, a jeweler’s loupe, a microscope, and other industry equipment. A completed certificate includes an analysis of the diamond’s dimensions, carat weight, clarity, color, polish, symmetry, cut and other characteristics.
A certificate will precisely point out a diamond's individual characteristics as well as be a useful tool when identifying a stone. When shopping for a loose diamond, considering stones that have a grading report will allow you to make an informed decision on which diamond will be ideal for you.
