All Blue Nile Signature Collection diamonds are certified by the Gem Certification & Assurance Lab (GCAL) in addition to being graded by the GIA or AGSL . This provides you a second authoritative analysis of your diamond. GCAL also verifies that your diamond meets all the specific quality requirements of the Blue Nile Signature Collection.
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.
In an F-colour diamond, no colour is visible to an untrained eye. As the least expensive diamond colour in the colourless range, F-colour diamonds display minimal colour difference from D- or E-colour diamonds and offer a lower price.
This diamond has no internal identifying characteristics, even when viewed under a microscope at extreme magnification. These diamonds are not graded flawless usually because of very slight surface markings or minor details in their polish. Diamonds of this grade of clarity are extremely rare.

Beautiful Engagement ring
I was so pleased with the engagement ring I purchased in late June. My fiancé was thrilled with how beautiful the ring is and the diamonds are exquisite. I'm very pleased that I purchased Signature Ideal stones.

Simple and Elegant
I have been searching for a simple, everyday, elegant diamond necklace and finally took the plunge. This necklace is perfect. Diamond is of very good quality and it is exactly what I was hoping it would be. Building my own necklace allowed me to get exactly what I wanted without paying a fortune.

I've bought an engagement ring.
I've bought a signature cut diamond ring. When I tried place an order, I wasn't sure if I liked it because it was difficut to tell its quality and authenticity from the picture. However, the skepticism was vanished immediately after I received the ring via Overnight Priority mail. It was a pure beauty. I am a man and a soldier. I don't really get sentimental over a little piece of jewelry, but it was differernt. It was a breath-taking. When I proposed to my girl with this diamond ring, she absolutely loved it and couldn't take her eyes off from it for a while.
I did not regret single penny I have spent on this ring.

diamond shipped to Europe
My girlfriend and now fiancee was delighted!!
I ordered a signature round diamond to be shipped to Switzerland. It arrived within the same week, and I was very happy how easy payment and customs procedure was (paid VAT by credit card over the phone). I would not have been able to find this type of quality diamond in the jewelry stores and especially not at this price. The diamond retailers in Switzerland are roughly 30-40% more expensive. I am very happy with my first Blue Nile shopping experience!
