We recommend considering carat weight along with two other influential characteristics: the overall dimensions and the cut grade of the diamond.Learn More
Signature Ideal cut: Top 1% of diamond quality - with precise proportions, polish and symmetry - allowing the diamond to reflect even more light than the standard Ideal cut.

A cut grade is the measure of a diamond's light performance. Cut with proper proportions, light is returned out of the top of the diamond. If it is cut too shallow, light leaks out of the bottom; too deep and it escapes out of the side.
E color: A "colorless" grade appreciated best set in platinum or white gold. Traces of color difficult for even trained eye to detect.

VVS1-VVS2: Very, very slightly included. Characteristics miniscule and difficult to see under 10x magnification, even to a trained eye.

No sparkle at all on these. Was counseled they were to be great at I color. And signature.
Diamond is beautiful, we both love it!
The signature round diamond on a Petite Engagement setting exceeded my expectations. The actual ring looks way better than it did on the website's photos. And yes, i mean YES, thats what I got and she loved how classic and elegant it looks. 2 words - Mission Accomplished! :) Thanks Blue Nile, will definitely come back for future diamond purchases!
