Before purchasing a diamond, you should expect to review a copy of its certificate, as this is your only guarantee of the quality and value of that diamond.

What's in a Certificate

A diamond certificate, also called a diamond grading report, diamond dossier®, or diamond quality report, is a report created by a gemologist, or gemologists, who have scrutinized the diamond and placed it under a microscope to analyze its dimensions, clarity, cut, color, finish, symmetry, and other characteristics.
