Where to get a fire stone in Pokemon White?

You can't get a Fire Stone in Pokemon White. The Fire Stone is exclusive to Pokemon Black.

Here's how you can get it in Pokemon Black:

* After beating the Elite Four: Go to the "Dreamyard" at the back of the "Floccesy Ranch".

* Speak to the girl: There's a girl standing there who will give you a Fire Stone.
