A Jewelers must have app

Wow! One bad thing about a Jewelers world is there isn't a great deal of useful apps. This one is amazing! With one click of a button, we can see the whole inventory. Each stone has a break down and a little bio about it. It also has professional quality pictures. This is a must for any jeweler that likes quality gemstones!!!!
