You can buy the Shiny stone at the pokeatholon dome
You can find one north of Goldenrod in the national park.
I believe you can get a Shiny Stone in HeartGold in the Pokèathlon Prize Corner after you get 5000 Points.
I believe it is something like a shiny Pokemon or shiny leaf stone. Getting a shiny Pokemon takes LOTS of luck, and a shiny leaf stone I think you find in patches of grass outside of Violet City in HeartGold. Hope this answers your question
