Cut: Blue Nile Signature Ideal

Fair | Good | Very Good | Ideal | Signature Ideal

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.

Colour: F

J | I | H | G | F | E | D

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.

Clarity: SI1

SI2 | SI1 | VS2 | VS1 | VVS2 | VVS1 | IF | FL

The inclusions in this diamond can be visible at 10x power magnification. Inclusions in diamonds with SI grade clarity might be visible to the unaided eye. SI1 grade diamonds are not as rare as VS1 and VS2 grade diamonds, so they are less expensive and present a great value.

She loves the ring.

Cut is the absolute most important of the 4C's and the Signature Round Diamond's are comparable to the very best cut diamonds from any other retailer. This diamond sparkles brilliantly in any light and appears much larger than it really is due to the cut.

Michael, DENVER CO – 16-Aug-2011

Looks great, cut, color, make this stone look a lot bigger than it it really is.

She said 'YES!!'

Very very beautiful Diamond and Ring with amazing quality and detail. Worth every penny!

Russell, Nottingham – 07-Aug-2011

It's so sparkly!

The diamond was beautiful. For something of similar size and quality from a local jeweler I would have had to pay more than twice as much. I was extremely happy with this diamond and so is she! The assistance over the phone is second to none. It takes moments to talk to a real person and the directories are kept to an absolute minimum on the phone. They are great people.

Joshua Daniel, Rapid City SD – 04-Aug-2011

Destined to be a family heirloom.

I was told buying a diamond on-line was like buying a house without a realtor -- so wrong! The selection is without comparison and the final choice stunning!!!

Stephen, CAPE NEDDICK ME – 01-Aug-2011

Amazing quality, amazing price.

Took my breath away when I opened the box. The diamond was set in a tension clasp allowing me to get a perfect view of it without worrying about dropping it and whatnot. The quality is amazing and the price was one step beyond that! I can't say that I've ever been more satisfied with an online purchase.
