Blue Nile refers to its top-of-the-line diamond cuts as Signature Cut diamonds. The jeweler says the Signature cut represents the top 1% of diamonds when you base diamond quality on cut. Expect to pay more for Signature cut diamonds, which are available as the round diamond on this page and as three more cuts you'll see on the following pages: Princess, Asscher and Emerald. Schematics on each page illustrate the cuts.
