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 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! !

I chose quality over quantity, and our signature diamond sparkles on all occasions, and easily outshines others when compared. It's colourless grading (IF / E)also seems to give it an edge over others we have looked at, but I am equally sure you could go to a V VS2 / I and not see the difference if you wanted a bit more rock for your budget. The sales person was extreamly helpful, and understanding when it came to dealing with a lack of information due to us men trying to surprise our loved ones. I had the ring delivered to my work address as Blue Nile is sympathetic to the surprise aspect required on these occasions, and delivery was exactly when specified, with email updates and easy tracking. While I was a bit worried about buying unseen, if you choose higher clarity and cut, other peoples ideas of "eye clean" compared to yours are not an issue.I have had an excellent experience with Blue Nile and happily recommend them to others.
