Established in 1931, GIA (Gemological Institute of America) is the world’s foremost authority on diamonds, colored stones, and pearls. GIA is a leading source of knowledge, standards, and education in gems and jewelry.
A GIA graded diamond will have a laser inscription that usually starts with 'GIA-' followed by an identification number on the girdle.
The inscribed identification number can be matched to a corresponding GIA certificate. The GIA certificate will tell you the exact carat weight, colour, cut and clarity of that specific diamond along with other characteristics. Below is a sample GIA certificate:
One step you should always go through when picking up a diamond you bought is to verify your GIA inscription in store and match it back to the GIA report you have been given. The GIA report can also be verified via GIA report check.
If your diamond is already set in the ring, the jeweller should always make sure that your GIA number sits between the prongs so that you can still verify the number.
Here is a quick video we created on how to check a GIA diamond in-store:
