Wonderful place to come to for advice on diamonds

I had been looking at stones for a long time and was getting overwhelmed with picking one. I asked for help and I was so happy with the result. They completely took my anxiety away and were so quick to show me some examples that were much better than what I had picked. This the place to go for good advice on diamonds!

I am not sure how this company makes money, but what a truly awesome and helpful service they provide, especially for free! Bradley was extremely helpful and responsive, even after business hours. I was able to secure a beautiful diamond at less than half the cost I could find on my own. This is one of few websites that everyone shopping for gemstones should know about.

Bradley was super patient love Stone algo

Bradley was super patient And walked me through the different options that were in my price ring. He took his time to explain why he would choose the ones that he did over some of the other diamond options I had originally looked at. there is nothing pushy or stressful about buying just the facts and they show you comparable options So you have plenty of choices. The best prices I've seen as well. Thanks so much for making this process easier. Their website is easy to navigate and allows you to plug in the prices and read the certifications and pros and cons. Another feature that I love is that it tells you how the ring looks visually compared to the carat size. There are so many great features on their website and you can tell the people really care that you find the right one. Highly recommend.

Trusted site! Shop with confidence!

Devin was extremely helpful and truly went out of his way to look into a center stone for me. Shopping for the perfect diamond that fits both the quality and budget is stressful but since discovering Stone Algo I have been able to make this large purchase with confidence knowing that I have the best deal. We found our perfect engagement ring and it is in part thanks to the dedicated individuals behind Stone Algo!

Found this site very helpful

Found this site very helpful, it's like kelly blue book but for diamonds. I found it amazing to have a 3rd party confirm that I got a good deal on my diamond purchase. I even opened up there chat box and someone replied to me almost instantly and answered a handful of questions. I'm just a normal guy from Oklahoma not a bot, I really found your site helpful. Thanks

SO HELPFUL!

I have found the StoneAlgo site incredibly helpful and have learned so much from the resources they provide! An additional plus is how helpful Devin is! It's great to receive advice and feedback from a neutral party who has no other interest but ensuring you get a diamond you love. Recommending this site to everyone moving forward. Thank you so much!

Find a Diamond here.

Start here for your diamond search! Using their speak to an gemologist tool works, but don't expect a swift reply. Instead use this site to make sure you're getting the most out of your dollars. Great search feature, useful information and comparison tools.

Devin was really helpful!

Devin was really helpful. I was browsing some diamonds and had a couple questions, and expected to hear back in a day or two. Devin replied to me via chat in just a couple minutes and addressed every question I had. He even offered to contact the retailer on my behalf.

Im thoroughly impressed. 10 stars

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.
