How to get the first Mega-Evolution stone for Charizard?

Question

When I got my Charizard, Sycamore gave me the stone that mega-evolves it into the black Charizard with blue flames. I know there's two mega-evolutions for Charizard, so does anyone know how to get the second one?

Answer 1

You get Charizardite X in Pokémon X, and you get Charizardite Y in Pokémon Y. You can only get both by trading it from the other version.
