How to check a GIA report

To check a GIA report, go to GIA Report Check on gia.edu, enter the report number, and compare what GIA returns with the paper and with the stone. The QR code on current GIA reports opens the same lookup. A match proves GIA issued that report — it does not prove the stone in front of you is the stone GIA examined.

How GIA Report Check works

1. 1.
   Find the report number. It is printed on the report, and GIA registers it in its global database.
2. 2.
   Go to GIA yourself. Type gia.edu into the browser and open Report Check. If you scan the QR code instead, look at the address bar before you trust the page: it should be gia.edu, not a lookalike.
3. 3.
   Enter the number. GIA asks for nothing else.
4. 4.
   Read the result. Report Check shows the data GIA recorded: date, shape, cutting style, weight, measurements, colour, species and variety, treatments and comments, plus geographic origin on an Identification & Origin report. For many reports GIA also offers a PDF copy, and for coloured stones Report Check can carry more detail on treatments than the paper.

A PDF from GIA is a facsimile. GIA marks such copies as digital representations that may not be accepted in place of the original, because the paper report carries security features a copy cannot reproduce.

If Report Check finds nothing

Re-type the number slowly; transposed digits are the usual culprit. If it still returns nothing, do not accept an explanation from the seller — a "new system", a "lab delay", a report "still being printed". Contact GIA directly, using details from gia.edu rather than from the paperwork, and hold off on payment until GIA answers.

Which GIA report is it?

GIA issues two main coloured stone reports, and they answer different questions:

• Colored Stone Identification Report — what the material is, whether it is natural or synthetic, and any detectable treatments, with a description and a photograph. It is available for loose or mounted stones.
• Colored Stone Identification & Origin Report — the same, plus GIA's opinion on geographic origin, for a limited list of species.

If a stone is being sold on its origin — Burmese ruby, Kashmir sapphire, Colombian emerald — the origin should appear on the report itself. An Identification Report says nothing about origin, however the seller describes the stone.

What to compare

Any difference is a reason to stop. Small rounding is not the issue; a different weight, a missing treatment line or a softened comment is.

Signs of an altered or fake GIA report

• No record, or different data. The plainest sign. Contact GIA before any money moves.
• Missing security features. GIA's guide to its pre-2026 Identification Report lists micro-printing, watermarks, a two-dimensional barcode, a hologram and sheet numbering, and GIA says its current coloured stone reports carry multiple security features. A plain printout has none of them.
• A link or QR code that leaves gia.edu. Forgers can print a working QR code that opens a copy of a lab's website.
• Only a photo or a PDF. If the seller cannot show the original paper, treat the stone as unreported until the lab confirms it.
• A stone that does not fit the numbers. Weigh and measure it, or have a gemologist do it.
• An inscription used as proof. GIA offers laser inscription on loose rubies and sapphires as an add-on, but an inscription is not proof on its own: GIA has reported stones — diamonds and a synthetic moissanite, in the cases it described — inscribed with real GIA report numbers that belonged to other stones.

Do not judge by design alone. GIA introduced redesigned coloured stone reports on 1 January 2026, so a 2026 report looks different from a 2025 one. Both are genuine.

What a GIA report proves — and what it doesn't

GIA has its own answer to the first gap: a Report Verification follow-up service for coloured stones. You submit the stone with its original report, GIA confirms whether they match, and the result comes back as a letter attached to the report.

Reading the fine print: padparadscha, emerald and origin

Padparadscha. GIA says it indicates padparadscha on its Colored Stone Identification & Origin Report when, in its opinion, a sapphire meets the criteria. GIA is one of the labs on the Laboratory Manual Harmonisation Committee (LMHC), whose shared rules make a colour-stability test mandatory for any padparadscha-like stone. If the colour shifts out of the range — for example fading towards pink — the name is not used, and the stone is reported as a pink or fancy sapphire instead. Heated stones can still be called padparadscha; diffusion-treated (for example with beryllium) and glass-filled stones cannot. So for a stone sold as padparadscha, look for an Identification & Origin report that names it, and check it on gia.edu.

Emerald. GIA reports describe clarity enhancement as minor (F1), moderate (F2) or significant (F3). Since December 2024 GIA can also identify the type of filler on request.

Origin. Origin appears only on the Identification & Origin report, and only for the species GIA covers — as of October 2026, alexandrite, demantoid, emerald, jade, opal, Paraíba tourmaline, peridot, red spinel, ruby and sapphire. A result of "inconclusive" is possible and honest.

Before you pay

• Ask for the original report, not a photo of it.
• Look the number up on gia.edu yourself, and compare every line.
• Weigh and measure the stone, or have a gemologist do it, and compare it with the photograph.
• For a stone sold on its origin or as padparadscha, make sure the report type actually states it.
• For a significant stone, consider GIA's Report Verification, or an independent check that the stone matches the paper.

What Everystone does about it

A free Registry record keeps a stone's details and its GIA report number in one place you can share, and once the report number is confirmed with GIA, the record says so. Matching that report to the physical stone — weighed, measured and looked at — is what an Everystone Passport adds: the report describes a stone, the passport shows it is this one. When you buy through the shop, every lot says how far it has been checked, and your payment is held until you confirm the stone. More on buying safely.
