Diamond Pricing

Now the bugs have been fixed, this app is awesome! Calculates the wholesale price of “mined” diamonds AND the first and only app to calculate wholesale price of “lab grown” diamonds quickly and easily. I love this app and recommend the 1 year subscription to keep your finger on the pulse for the latest wholesale diamond price list.

A MUST BUY for anyone wanting to compare diamond sizes and appreciation rates! I am not aware of any other app with this capability. In doing research on the app developer it looks likes he has a strong background in the gem industry and is the founder of the Troy Diamond Report and has put together an app that both industry and lay people can use easily! I am looking forward to being able to gain a better understanding of not only the value of any diamond purchased but also of the appreciation value attached. So happy I found this!
