How do you get a shiny stone in Pokemon FireRed?

Answer 1

On Iron Island, you can find the Shiny Stone in the

back exit of the cave. You can find another Shiny Stone on the southern end

of Route 228, if u hav a Pokemon with the pick-up ability, there's a slight chance u might get one, the only other way is underground...sadly, I've found all of them and used them...now i actually need one and I've been digging in the underground for weeks...glad i could help, if i did.

P.S. if u go for the underground, goodluck.

Well, the thing is in fire red your in Kanto and route 228 or whatever it is, is not introduced to you yet.
