Everstone


 * }

The Everstone (Japanese: かわらずのいし Unchanging Stone) is a type of held item introduced in Generation II. It is an out-of-battle effect item that prevents the holder from evolving.

Price
In the Generation V games, the Everstone can be sold to an item maniac inside the Icirrus City Pokémon Center for 1000.

In the overworld
A Pokémon holding an Everstone cannot evolve by level-up or trade. (It does not prevent a Pokémon evolving via Evolution stone.)

From Generation IV onward, the Everstone fails to prevent from evolving. If either or  holds an Everstone when traded for the other, neither can evolve.

Natures
In and, if held by a female Pokémon or  in Pokémon Day Care, bred Pokémon have a 50% chance of having the same Nature as that parent. In Generation IV, this does not work if the parents come from games in different languages (due to the Masuda method).

In and, if held by either parent in Pokémon Day Care, bred Pokémon have a 50% chance of having the same Nature as the parent holding the Everstone. In Generation IV, this does not work if the parents come from games in different languages (due to the Masuda method).

In and Generation VI onward, if held by either parent in Pokémon Day Care or the Pokémon Nursery, bred Pokémon are guaranteed to have the same Nature as the parent holding the Everstone.

Regional variants
If held by a Pokémon that has regional variants in the Pokémon Nursery, bred Pokémon will be the same regional variant as the parent regardless of the region they are bred in. (Normally, hatched Pokémon are always in the form corresponding to the region in which they were bred.)
