A note from Devin & Jay
(the two guys who started this thing)

StoneAlgo began as a personal quest to find the right diamond at a fair price. Nowadays we're helping our users discover their perfect diamond at the lowest price from the top online jewelers. Every day we algorithmically search through millions of diamonds to find the best deals without compromising on quality.

Our business model is similar to Kayak or SeatGeek: completely free for our users but we charge the jewelers a small fee to list their diamonds on our site. We experienced how stressful this search process can be firsthand. Our goal is to make your search easier.

We hope StoneAlgo helps you find your perfect diamond.
