Is a GRA certificate real?
A GRA certificate is a printed card that moissanite sellers put in the box, with a grade and a number you can look up on a GRA website; it is not a report from an independent gem laboratory. A gemmologist who looked into GRA in 2021 found its reports imitated the look of GIA’s and judged them unreliable, and in 2023 GIA warned that unordered rings were arriving with GRA reports, possibly as a “brushing” scam (American Gem Society, 2 March 2023). Treat the card as packaging: a 10x loupe or a moissanite tester tells you more about the stone.
What a GRA card is, and what it is not
GIA and IGI examine a stone themselves, file the result under a number you can look up on their own websites, and laser-inscribe the number on many stones. A GRA card is different. The American Gem Society, republishing a GIA alert, gives the name as Gales Gemological Research Association, and the gemmology site Le Gemmologue found GRA reports pointing to at least four different websites. When Le Gemmologue examined stones that came with GRA papers in 2021, bought online by a student and by dealers, the reports turned out to copy the design of a GIA report; several of the stones were moissanite, and some were other materials. We found no evidence that GRA examines the stones its cards describe.
Why it does not make the stone fake
GIA says all moissanite used in jewellery is lab-created, and it is now inexpensive, so the printed grade is the weak point more than the stone. The colour and clarity on the card are the seller’s claims. A 10x loupe (doubled back facet edges) or an electrical moissanite tester confirms what the stone is; see is moissanite on Amazon real?
Got a moissanite ring you did not order? The GRA brushing scam
On 2 March 2023 the American Gem Society republished an alert from GIA. GIA had taken more than 50 calls in three months from people in California, Texas and elsewhere who received unexpected packages of low-quality jewellery. Some pieces came with GRA reports saying the stone was moissanite; others came with counterfeit GIA reports calling it diamond. GIA said it was not clear why the items were sent, but that it could be a brushing scam, in which scammers use people’s personal information to post false online reviews. The US Federal Trade Commission’s advice (August 2026): you do not have to return or pay for something you did not order; tell the marketplace, such as Amazon, so it can look into the seller; change your shopping passwords; check your credit report; report it at ReportFraud.ftc.gov; and do not scan a QR code on a note in the box, which can lead to a phishing site. Any GIA diamond grading report issued since 1 January 2000 can be checked on GIA’s Report Check at gia.edu.
How to look up a GRA number (it confirms the card, not the stone)
Type the number from the card yourself into the GRA website printed on it, rather than following a link or QR code that came with the package. A matching record shows that a card was issued with that number; it does not show that anyone examined your stone. When Le Gemmologue tried this in 2021, the lookup returned a report that roughly matched the stone, and the GRA websites changed within about three weeks. So use the lookup to check that the card matches the listing, then check the stone itself with a loupe or a moissanite tester.
When a certificate does matter
For a lab-grown or mined diamond, where the price is higher, ask for an IGI or GIA report and look the number up on the laboratory’s own website. Since 1 October 2025, GIA no longer grades lab-grown diamonds on its D-to-Z colour scale: it describes them as “Premium” or “Standard” (see IGI vs GIA and how to check a report number).
Frequently Asked Questions
Is GRA the same as GIA?
No. GIA, the Gemological Institute of America, is an independent gem laboratory that examines each stone it reports on. GRA is a different name; Le Gemmologue found its reports imitated the look of GIA’s, and in 2023 GIA warned of unordered jewellery arriving with GRA reports.
Does moissanite need a certificate?
Not really. It is lab-made, inexpensive and easy to identify at home. Buy for the setting, metal and return policy, not for the card.
Does a GRA number lookup prove my moissanite is real?
No. It shows the card exists in GRA’s records. Check the stone itself: doubled back facet edges under a 10x loupe, or an electrical moissanite tester.
I got a moissanite ring I never ordered. Is it a scam?
Probably a brushing scam: GIA’s 2023 alert described unordered jewellery arriving with GRA or counterfeit GIA reports. The FTC says you do not have to return it or pay for it, but tell the marketplace, change your passwords and do not scan any QR code in the box.
