Trust & Authenticity

Verify Report

Check any IIGL grading report against the laboratory’s own record — type the report number, or scan the QR code printed on it.

How to Verify a Report

Step 1
Find the report number
It is printed on your IIGL report card, beside the QR code.
Step 2
Type it, or scan the QR code
Enter the number above, or scan the code with this page or your phone’s camera.
Step 3
Match the details
The product, weights and characteristics shown must match the report in your hand.

Anyone can print a card. Only a report in IIGL’s own records verifies here, so what you see is the laboratory’s record, not the card’s.

Check each character first. A report can also be withheld from public verification; contact us with the report in hand.

The item’s details only — never the owner’s name, number or what was paid.

Spot a fake report
A printed report can be copied or altered. Only a number that opens here was issued by IIGL.
Match the stone
Compare the weight, measurements and photograph online with the item in your hand before you pay.
Buy and sell with trust
Share the verified link with a buyer or seller, so both sides look at the same record.

Ensuring Authenticity
A certification report is a gem’s birth certificate, documenting its origin and characteristics and offering indisputable evidence of its identity — so you get exactly what you paid for.
Quality Assessment
A diamond grading report delves into the 4 Cs — carat weight, colour, clarity and cut. A certified gemologist evaluates each with precision, so you can understand a gem’s quality and decide with confidence.
Enhanced Value
Certification by a recognised authority adds a layer of trust to your stone, and that trust can translate into a higher resale value should you ever decide to part with it.
Conflict-Free Assurance
Certification supports the ethical sourcing of gemstones. Verifying your gem’s report contributes to the movement against conflict diamonds and to sustainable practice within the industry.
Investment Protection
Gems often serve as investments. A verified report guards against counterfeit or misrepresented stones and helps secure your financial interest.
Peace of Mind
Knowing a gem has been examined by experts and authenticated by a reputable institution removes doubt — so you can simply enjoy its beauty without worry.
