Before purchasing a diamond, you should expect to review a copy of its GIA Diamond Certificate as proof that it has undergone an unbiased, professional examination.
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.
Boston 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.
