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 offers an exceptional balance of color and cost in the near-colorless range. If you choose an H-color grade diamond, you can buy a larger diamond for the same price as a higher color grade. The very slight tint is generally not noticeable.
This diamond has very few, very tiny inclusions. The inclusions in this diamond are virtually unidentifiable even when viewed under a microscope at 30x power magnification. Diamonds of this grade of clarity are extremely rare.

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!
