you can use a water stone on lombre
Sunkern and Gloom use a sun stone Lombre, Staryu, and Eevee use water stones.
you use it, assuming you have a Pokemon that requires a water stone to evolve instead of just simply leveling.
Equip the Warrior with the Stone and then in a battle or a training session, use it on that Pokemon. And voila.
Lombre and etc
