You can't buy them in Diamond or Pearl, but there's one in Sunyshore City. If you already used that one, try digging underground. You'll find one eventually.
It depends... What Pokemon is it? (Not that I know...)
Dawn stones are only available in Diamond and Pearl.
there are no dawn stones they were not introduced until Pokemon diamond and pearl
you can't get underground in soul silver. if you're looking for stones trade Pokemon from diamond, pearl, or platinum holding them.
trade diamond from Pokemon diamond onto Pokemon pearl
I only know one. ( sorry ) it is... The thunder/lightning or which ever one that's electric can evolve pikachu into raichu.
You trade Magmar from Pokemon pearl,diamond,or platinum to ether Pokemon pearl,diamond,or platinum.
No, luxray does not learn lightning star in Pokemon diamond. Its one of luxray's moves on a Pokemon card, but lightning star doesn't exist on the shows or the video games. Its weird, I'd really like it to become a real move in diamond or pearl but some moves are just made up for the card game to be different.
THE POKEMON THAT ARE NOT FOUND IN DIAMOND AND PEARL ARE:MANAPHY PHIONE
You can get Palkia in Pearl, otherwise you have to transfer Palkia from Pokemon Pearl to Pokemon Diamond.
diamond
No, you can't catch Deoxys on Pokemon Diamond & Pearl unless you have cheats. You can transfer it from your GBA to Pokemon Diamond and Pearl though
