A Diamond Grading Report documents the specific characteristics of a diamond. These reports are issued by the Gemological Institute of America (GIA), which is among the most respected organizations in the diamond industry.
GEMPRINT® is the world's most sophisticated, non-invasive, positive identification technology that records the unique optical 'fingerprint' of each diamond. Just like a human fingerprint, every diamond has a unique Gemprint®. Invented in 1976, this patented and proven technology has been used by the FBI and Canadian Government.
A Diamond Quality Document, issued by the American Gem Society Laboratories (AGSL), is universally accepted and respected by the jewelry industry as a document of authenticated quality.

It's a Y-E-S!!! :) she loved the ring!
The signature round diamond on a Petite Engagement setting exceeded my expectations. The actual ring looks way better than it did on the website's photos. And yes, i mean YES, thats what I got and she loved how classic and elegant it looks. 2 words - Mission Accomplished! :) Thanks Blue Nile, will definitely come back for future diamond purchases!
