There is no such thing as a Crystal Onix in the Pokemon games series. It was only in the Pokemon anime.
You can find an Onix in Dark Cave or in Victory Road in the main game.
rock tunnel
relic castle
Onix can be found on seven island, six island and rock tunnel.
gravellers, golbats, machokes, steelix, onix, medicham, chingling... all the normal mt coronet pokemon.
you can evolve him into steelix otherwise i think not. heres a drawing of an ass ( Y )
You find it in Orbegugh Mnes or on Iron Island
Brock isn't in Diamond and Pearl. He is in another game but i forgot which one it was. Hes in Pokemon LeafGreen and FireRed as the frist gym leader and there he got geodude and onix
