You can buy one from the PokeMall.

Sorry, there's only a thunderstone in the mall. Talk to a man on the 3rd floor to get it.
Three places. One, if you go throughout all of Mt. Moon, I'm also sure you can find one while traveling the game, and I think you can buy them at the PokeMall.
If you are really lucky, you will be able to find one by digging underground. I've tried it, and only got a Leaf stone, a Sun Stone and a Moon Stone. Sigh. Do you want a Shield fossil? I've got 992 (apparently) and they're Pearl only! *wink wink*
