Good Cut Diamonds

The cut of a diamond refers to how precisely those intricate facets of the stone have been cut. Diamonds with a cut grade of “Good” are among the top 25% in cut quality. When you choose a diamond with a Good cut, most of the light entering the diamond will reflect back to you, delivering the brilliance you love. Every diamond sold comes with a GIA certificate outlining the full grading report of your diamond.

Excellent Ring and Service

This truly was the perfect setting for my future wife. The delicate twist and double row of French pave truly makes the stone POP. I got a .93 carat diamond with good cut clarity and colour and the setting makes it look bigger. Her family is convinced that it’s over a carat. The ring has real wow factor and I’m very pleased

Great experience

I was skeptical to purchase an engagement ring online but Blue Nile made it so easy and feel extremely safe. I couldn’t be more pleased with the ring and my fiancée is thrilled as well. We’ll be purchasing our wedding bands from them next.
