How do you get the evolutions of Eevee?

You need water stone to get vaporeon, thunder stone to get jolteon and fire stone to get flareon. To get espeon, eevees happines have to be max and then level it up in day. Same thing to umbreon, but in night. Level eevee up in moss rock (its in sinnoh) to get leafeon, and level eevee up in icy rock (its in sinnoh too) to get glaceon. Moss rock is in eterna forest and icy rock is in route 217.
