I just downloaded Getgems for Android,   i can't even add contact... any explanation ?

If i get it,  

there are 100M Gemz.    And price on Polo is currently around 0.000025Btc.    So a Gemz cost 0.01 Dollar.

I mean, if x10 happens, we will be at 0.10 dollar/Gemz wich seems to me more than fair for a "social currency".

So my question is : Are Gemz divisible ?
