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. -- Kiwibd, 2019-01-24 ### *---- "Crashes" Crashes immediately. -- Johnboy4562, 2018-12-15 ### ***** "Diamond" Awesome -- A 10 year old kid boy, 2013-08-07 ### ***** "DIAMONDMASTER" 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! -- SiliconValleyBD, 2013-05-10 ### *---- "WARNING: DO NOT BUY!!!"
