What is a GIA Diamond Certificate?

A diamond certificate, also called a diamond grading report, diamond dossier®, or diamond quality document, is a report created by a team of gemologists. 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, color, polish, symmetry, and other characteristics. Many round diamonds will also include a cut grade on the report.

The GIA Diamond Grading Report includes an assessment of the 4Cs – Color, Clarity, Cut, and Carat Weight – along with a plotted diagram of its clarity characteristics and a graphic representation of the diamond’s proportions. For standard round brilliant cut diamonds falling in the D-to-Z color range, the report also includes a GIA Cut grade.

The GIA Diamond Dossier® includes an assessment of the 4Cs – Color, Clarity, Cut, and Carat Weight – plus a microscopic laser inscription of the GIA report number for easy identification. For loose, D-to-Z color diamonds only, weighing 0.15 – 1.99 carats.

GIA Diamond Certificate - Boston Diamond Studio - Jewelers BuildingBoston Diamond Studio uses cut grades provided by GIA whenever these are available. Many diamonds graded by the GIA prior to January 1st, 2006 do not have such grading. If a cut grade is not provided, Boston Diamond Studio defaults to a proportion system that uses measurements of depth and table to determine the amount of brilliance in a particular diamond’s cut.
