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.
All Blue Nile Signature Collection diamonds are certified by the Gem Certification & Assurance Lab (GCAL) in addition to being graded by the GIA or AGSL. This provides you a second authoritative analysis of your diamond. GCAL also verifies that your diamond meets all the specific quality requirements of the Blue Nile Signature Collection.
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.

I'm glad I went with the Signature cut. I get tons of compliments. One thing is though is that the stone doesn't seem like it's set correctly in the ring. it might be slanted slighted. hardly noticeably but I considered sending it back for adjustment.

I know little about diamonds. I informed myself about them online and on the blue Nile website. Based on customer satisfaction and price I made an easy decision, and best of all she loved it and better still, she said YES! !
