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.
This diamond is cut to more exacting standards than the finest graded cuts currently available. With a Signature cut, this diamond reflects the maximum brilliance. This is our finest grade of diamond cut.
This diamond, when cut to ideal proportions, produces a warm brilliancy not found in the higher grade colors. I-color diamonds are less expensive than other diamonds, so you can buy a larger diamond for the same price as a higher color grade. Note: If this diamond has medium or strong blue fluorescence, its slight tint will be partially masked, making the diamond appear whiter to the eye.
The inclusions in this diamond can be visible at 10x power magnification. Inclusions in diamonds with SI grade clarity might be visible to the unaided eye. SI1 grade diamonds are not as rare as VS1 and VS2 grade diamonds, so they are less expensive and present a great value.

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 was a bit nervous buying a Diamond Engagement Ring online, however Blue Nile's quality, coupled with their excellent educational readings helped make the purchase one I did not regret. The diamond looked great, and because of the educational readings from Blue Nile, I even decided to go with a smaller carat size, but a better cut! =))

Happy endings and new beginnings
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! !
