This ring turned out way cooler than I could have ever expected and looks nicer than rings 10x the cost! It turned out perfect with a rough diamond!

Cameron G.

The ring is fantastic. Great selection on different shapes of raw diamonds. If you’re looking for something simple, different, and classy, use the Raw Stone!

I really liked the selection that The Raw Stone provided. When I had trouble creating the ring I wanted, help was immediately given to me. Very pleased with their service.

Cord V.

Excellent product and exceptional customer service The ring is gorgeous and my fiancé loved it! (And said yes!!) The ordering process was smooth, and the customer service I received was exceptional. I had questions about sizing and then resizing, and Kerin was so kind and helpful throughout the process.

Madelaine W.

Amazing service and stone. Great customer service and beautiful stone, the pictures don’t do justice to the beauty of the stone. Thanks

Ricardo E.

Kerin created a wonderful buying experience when I was shopping for an engagement ring. From our initial phone call, she was able to advise and quickly bring together my vision with a carefully curated set of uncut diamonds. The final product is astonishing in its simplicity and elegance - it really reflects the feelings I wanted to materialize with this ring. Thank you so much!
