ExJewel's algorithm is very powerful! The first time I tried it, it was still on an excel sheet and it was already very precise. Now, with millions of data and an even more powerful algorithm, it even recognised a Tourmaline from a Ruby!

My experience with ExJewel has been a special one. The intuitiveness of the platform, responsive customer service, and thoughtful feature set is a breath of fresh air. FYI. Can't believe that we can finally appraise synthetic diamonds with transparency!
