I highly recommend this place to anyone… I highly recommend this place to anyone who's looking for the diamond. It's the most helpful tool in the journey of choosing the stone. They offer the visual size, price history, GIA check, comparing and the specialist (Devin) is available anytime to answer the questions. I'm so impressed by their great service, and all of the information and service are free! they don't ask any email or phone number before releasing the answers, everything just shows up on the website！so simply and transparent, love them!

StoneAlgo is a Tremendous Resource StoneAlgo was a tremendous resource during my search for the perfect diamond. The cut score was a terrific way to hone in on the best candidates when faced with the overwhelming number of options available online. Furthermore, Devin and Jay were always available to look over any options and share their knowledge. With their help I was able to avoid many pitfalls when choosing the right stone (thanks guys!).

this site is awesome this site is awesome. The co-founders have helped me on more than one occasion through the chat option. They were so nice and honest. They helped and gave me advice on 2 stones I was considering. Their advice and opinions are unbiased and you can tell they generally really just want to help with no ulterior motives. Highly recommended. I love the free diamond check.

Confused with Diamonds? Look no further. I found this site at 1:30am in the morning. I got off the site at 3:30am. Did i think that reading about algorithms on diamond sales would be interesting? Nope. Was it? Sure was. The transparency of all the data-models coupled with the refined support that Devin personally provides makes StoneAlgo stand shoulders above any peers/competitors. The current over-marketed and hyped diamond industry really needs a rational, fact-based and unbiased approach that StoneAlgo brings to the table. StoneAlgo helps even the most novice diamond hunters become functional enough to make informed and decent decisions on such an important and emotional purchase.

Highly recommend Stone Algo I am VERY grateful to Stone Algo for saving me from a would-be terrible purchase. I ran the GIA of the stone my local jeweler was offering, which revealed mediocre quality (and small "visual carat size") for an overpriced diamond. Will be using their search engine now to find better/cheaper options. Highly recommend!
