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 is nearly colorless. A diamond with G-color has an extremely faint tint that is only noticeable to a trained gemologist. G-color diamonds make for beautiful jewelry and they offer an outstanding value, since they are less expensive than the colorless grades, but appear to the eye to be colorless when mounted.
This diamond has few, very small inclusions. The inclusions are very difficult to see under a 10x power magnification, and are almost never visible to the unaided eye. VS1 grade diamonds present an excellent value in clarity because they are typically free of visible blemishes, and they are less expensive than higher clarity grades.

Exceeded our Expectations
My wife and I couldn't be happier with the ring we purchased. Blue Nile was recommended to us by a friend and I have to admit I was a bit nervous about buying a diamond online at first because there is so much variation in diamonds of the same cut, color, and clarity. However, the GCAL certification Blue Nile provides on Signature Ideal Round diamonds allowed us to see the true quality of the diamonds and alleviated our concerns. Again, we couldn't be happier. Thank you!
