What Is The GIA?

GIA is the world’s most respected gemological laboratory, entrusted with grading and identifying more gems than any other lab. Located in major gem and jewelry centers around the world, GIA laboratories are staffed by expert diamond graders and gemologists, whose work sets the standard for grading practices worldwide.

The grading reports produced by the GIA are always very accurate and myGemma places a significant amount of trust in the GIA reports. So much so that for all Round Brilliant stones with genuine reports, we can offer a specific dollar amount for your diamond item. For all other GIA certified diamonds we will provide you with a highly competitive price range based on the details of the certificate. Simply provide us with the cert number or a copy of the GIA report in order to receive an accurate price range.
