Diamond™ Alternative

Tiffany Style Round Cut
My fiancé and I couldn't be happier with our ring. Not only is the stone flawless and the ring stunning but it was a fraction of the price, leaving us with more to spend on our wedding!

-Corey




Prague Halo
This ring is a wonderful, elegant piece, I got the large stone and rose gold, and totally blew her away. Everyone who sees it loves it. The shine is amazing.

-Dom




Gwyenth Round Cut
Stunning. Incredible. Unbelievable value. Just some of the things that come to mind with this ring…I never would have been able to get a mined diamond close to this size for 5 times the price!

-Dave




Valencia Princess Cut
The stone is gorgeous, and ring itself looks very elegant and high-end. [My fiancée] gets complemented on it where ever she goes.

-Mike




Bali Round Cut
I LOVED the idea of a more sustainable diamond look-alike and the price allowed for me to get a much larger carat size too. I expected it to look lovely, but what I wasn't expecting was for it to also "feel" like a real diamond…It really feels like a win-win-win to me (perfect cut/clarity/color + sustainable/socially responsible + still affordable and twice the size).

-Melissa




Montreal Round
I am in love with this ring! I have never been so excited to put on a piece of jewelry every single day. Literally, all I do all day is stare at my hand. I have gotten so many compliments on it-- the sparkle can't help but catch the eye. I am so happy that I took the time to research diamond alternative stones. Diamond Nexus truly does produce heirloom quality jewelry.
