StoneAlgo Avis 

During my diamond research, this was the perfect resource beyond the GIA report. Who knew that even in an excellent cut diamond there's so much variation ! The cut score helped me narrow my choice. I connected with Devin on chat and he patiently answered all my questions and cleared my doubts. I am happy to say that I picked a diamond with a 9.6 cut score and am blown away by the sparkle. Wishing Devin and his team good luck and a sparkling future in the diamond industry.

Spoke with Devin this morning about a diamond purchase, and he did not disappoint. I actually wish I spoke to him before purchasing. He is honest and truly knowledgeable. I highly recommend doing your research using stonealgo prior to and during your diamond selection!

Awesome site! Very helpful resource and will highly recommend it to others. The GIA lookup tool is incredible, I used this a few times when at diamond stores. The site really helps put you in the driver's seat for this process. Devin was very helpful and knowledgeable.

I had Devin after 3 minutes posted my question. He was very professional and gave me answers exactly what i asked for. They were quick on answering questions and knowledge about diamond industrial. Good service. I felt more comfortable after talking to him to make my 1 st purchase. I learned so much thank you Devin . Recommend for anyone

I started to learn from this website to help my knowledge about diamond and pricing
Finally, I get a new stone to update my wedding ring , I’m very happy for ur help and grading diamond ❤️❤️❤️❤️❤️

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!).

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!

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!

They were completely off in their pricing estimate. The price they had listed on their website made no sense and was not comparable to any other price I was quoted for this item

I was looking for a 2 ct diamond from Bluenile. I did all my homework and studied the 4 C’s . I also studied what % and angles would give me the diamond with the highest brilliance etc. By using the StoneAlgo calculator , I was able to find the best cut diamond at the best price. My diamond is breathtaking. Thank you for offering this site , free of charge , might I add! I would recommend never buying a diamond without it.

Used this site for my ring search. This site is a must use for research for anyone that is shopping for a diamond.
I've compared multiple sites, wholesalers, retailers with their cut ratings and the algo used for their ratings will give you the best advantage. From all the sellers, stores, and peers I've talked to when starting this journey this resources was the most useful.

Can't rave enough about how helpful StoneAlgo is. Buying a diamond is stressful and confusing...possibly even more so online. StoneAlgo allows you to pull up and compare stones from multiple online sites, ranks them, rates their cut quality and suggests alternate stones, all with the intent of getting you a stone that meets your criteria at the best value. StoneAlgo's proprietary algorithm takes into account the many dimensions of the stone to generate a cut quality rating, and cut quality is what makes a diamond sparkle. Devin, one of the founders of StoneAlgo, was very responsive when I started an online chat with questions, and his in-depth, comprehensive answers demonstrated these guys know what they are talking about. StoneAlgo is not trying to sell you anything, it's intent is to educate and help you get the best value. Only wish I was buying diamonds regularly so I could use it more often! Thanks StoneAlgo :)

Very helpful in trying to make the largest purchase of my life thus far! Brings clarity to a very opaque market.

The perfect elimination tool to help you decide between a few stones A++

As an adjunct to my personal search for a diamond, StoneAlgo has been a great resource. The search is very easy to use and the comparison report is excellent. I even had a few questions for the owners and they wrote a thorough, prompt reply. Thank you!

I reached out to the Reddit community to get some thoughts on a diamond I was considering for an engagement ring and Devin ran the diamond through StoneAlgo and gave me his personal thoughts. I can't believe how incredibly helpful it was! I did end buying said diamond and it was exactly what StoneAlgo predicted. Additionally, I used it to verify other options even though I had already made my decision to help give me the peace of money that I made the right one!

A++ StoneAlgo is a godsend for folks trying to make educated decisions in a very confusing industry!
