Once you have all the other dragons and have upgraded the cave/island/nursery etc. there is really nothing to spend gems on except for speeding up breeding on new limited dragons.

And yes it also requires luck, even a couple of hundred gems won't get people a Gemstone dragon in the first day or two unless they also get very lucky.
