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 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

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!

Devin is SOOO AMAZING Devin is SOOO AMAZING. Honestly i didn’t think he was going to reply back to my messages. Especially because i was super annoying and asked him about 4 different GIA diamonds. Not only did he reply back but was extremely detailed, patient and gave me a list of better options of diamonds. Im thoroughly impressed. 10 stars
