How do I verify my WGI certificate?
Enter the certificate number printed on your WGI card on the Verify Certificate page, or scan its QR code, to see the official online record of your jewellery.
Are lab-grown diamonds real diamonds?
Yes. Laboratory-grown diamonds have essentially the same chemical, physical and optical properties as natural diamonds; they differ in origin.
My certificate number is not found. What should I do?
Check the number exactly as printed on the card, including letters. If it is still not found, contact WGI with a photo of your card.
How do I submit an item for a report?
Contact our London laboratory in Hatton Garden or one of our offices to arrange submission.
