I don't think it's worth it. The chance to get the gems is very, very, very small. And that's just the 500 gems; I suppose the 1000 and 10000 have even smaller chance. You may get lucky in the first draw, but if that's not the case, then I recommend to not try again.

Think like this, once you finally get 500 gems, you probably have spend 594 gems.
