I read the reviews on this app. Just recently bought a diamond and wanted to test this app out. Same results as most. It overprices the diamond thus making this a pretty useless app. It over priced the diamond I bought by 50 percent. So, if your in the market for a diamond dont use this. This app will help you get ripped off.
However, if you want to put this app on your phone so you can brag to your friends about the diamond you just bought, then this is for you. It will overprice the diamond and make you look like a big spender.
