So you've shortlisted a diamond and analyzed it under the scopes. You like what you see and everything looks perfect under the scopes, and you're just about to place a deposit for it. But how do you know that this is really the diamond you're buying? Could it be a 'sample' diamond? Or how I know that when I'm collecting my ring, will it be the same diamond? This is what the diamond's laser inscription number is for!
Each certified diamond will have a laser inscription number that is inscribed on its girdle (edge). It is a unique serial number that is assigned to your diamond. The serial number would tally to its certificate. This is how you can verify if this diamond tallys with its original certificate.
In JannPaul, upon purchasing and collection, we use a 40x magnification equipment to show you your diamond's inscription number. This is then tallied with its certificate.
You may also download or verify the softcopy of your GIA or AGS certificate online at, GIA's website or AGS's website.
After you've shortlisted and analyzed your diamond under the scopes, it is absolutely necessary to check it's laser inscription number to match its certificate. Here are some easy steps to follow.
- Ensure the GIA certificate you're viewing is the original certificate and not a printed or photocopied version.
- Before confirming your purchase, check your diamond's inscription number to match with its original certificate.
- After your ring has been crafted and ready for collection, check its inscription number again to match its certificate.
- For future servicing, such as re-sizing, re-polishing, etc. don't forget to check its inscription number again.
