A few things that need to be fixed up:

1) Grammar. It's not terrible but it could use some work.

2) Some sort of limitation on the powers are needed in order to not make them too OP

3) This can only be a flaw if this impedes his ability to be aware of his present situation and I think that it's really improbably for it to have his mind on it 24/7 when his own life is endangered or something else drastic is happening. I mean if it's happened recently sure but eeeeeeeeh I don't know how to feel about this. 

4) It'd be nice to know more about who this Jack guy is, other than he's his friend. Maybe how he befriended a human. Things you should add to the history probably. I know I said you don't need to include it if your gem is young enough but I meant so young that nothing really important happened and clearly something important happened to Azurite.

5) The first sentences of your writing example are already telling instead of showing and we don't get much of an idea of his personality other than he's not a coward and that he was (I'm guessing this changed) a much more talkative. Everything else is told to us rather than shown. Don't get me wrong it's a nice snipet for history but still.

Other than this everything looks good.
