Uninformed app!! Beware
I design and create jewelry with real stones and gems. I was under the impression that this would help me to determine the quality of the stones and gems that I do have possession of. However, high end turquoise even though I asked four times got a different response each time with the same picture. As far as I can see, this is a huge waste of money and my time! I’m so sorry that I made the mistake of downloading this app thinking that it would be a responsible app. However, responsible is definitely not what this is! I would give it a -5 or -15 stars if that were possible. So, if I were to make a recommendation, it would be please do not buy this app!
