Questions
Frequently Asked Questions
Everything you need to know about GRA certificates and moissanite grading.
What is a GRA certificate?
A GRA certificate is a grading report issued for moissanite gemstones. It documents the stone's shape, measurements, carat weight, color grade, clarity grade, cut grade, polish, symmetry, and fluorescence — giving you an independent record of your gemstone's quality.
Where do I find my GRA number?
Your GRA number is printed on the physical certificate that came with your moissanite.
My GRA number shows no result. What should I do?
Double-check that you typed the number exactly as printed, with no spaces. If it still cannot be found, contact the shop where you purchased your stone.
Is moissanite the same as diamond?
No. Moissanite is silicon carbide, a distinct gemstone that is nearly as hard as diamond (9.25 on the Mohs scale) with even more fire and brilliance. It is a popular, ethical, and affordable diamond alternative — and GRA certificates grade it using diamond-style criteria.
Does verification cost anything?
No. Checking a GRA certificate on this website is completely free, with no account required.
