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*
You can buy one from the PokeMall.
and if you surf across to the right from driftviel city where you see the old man walking back and forth you will find one. Black city you can find one if you have the right people
As it's an evolutionary stone it's very rare, but after you receive the Explorer Kit from the man in Eterna City (the house beside the Pokemon centre) you can go underground and dig one out. But like I said they're very rare so it might take you a while to find the right one, I've found that the Thunderstone and the Fire Stone can be found more often than the Water Stone. Hope I helped.
You can get one in the Solacean town ruins.
