A Pokémon [[held item|holding]] an Everstone is [[evolution prevention|prevented]] from [[Evolution|evolving]] using certain [[methods of evolution|methods]] depending on the games.

In all games where the Everstone is available, this item prevents any of the methods of evolution triggered by gaining a [[level]] in {{pkmn|battle}} or by consuming a [[Rare Candy]]. This includes but is not limited to leveling up [[List of Pokémon that evolve at or above a certain level|at or above a certain level]], or [[friendship evolution|with high friendship]], or in certain locations, or knowing a certain move, holding a certain item, and so on.

If a Pokémon is able to [[trade evolution|evolve by trade]] with no held item, then it is possible to prevent this evolution by trading it with a held Everstone. However, this does not work in [[Generation III]] due to [[List of glitches (Generation III)#held item loss glitch|a glitch]] which causes those Pokémon to consume whatever item they are holding (including the Everstone) while evolving. In [[Generation II]] only, the Everstone is able to prevent {{p|Kadabra}} from evolving into {{p|Alakazam}}. From [[Generation IV]] onwards, a Kadabra still evolves into Alakazam while holding an Everstone due to an explicitly programmed exception.

Only in Generations {{gen|II}} and {{gen|VIII}}, a Pokémon holding an Everstone is unable to evolve by using an [[Evolution stone]]. In Generation VIII, the text "Cannot use" appears when attempting to use an Evolution stone to evolve a Pokémon that is holding an Everstone.

In {{B2W2}} 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. If both parents hold an Everstone, each parent has an equal chance of passing down their [[Nature]].

* In {{g|Scarlet and Violet}}, a question on the Biology class's Final Exam references this item, specifically its interaction with [[Evolution stone]]s: "If a Pokémon is holding an Everstone, will using an item that induces Evolution, such as a [[Fire Stone]], cause it to evolve?". In earlier versions of the games, <!--Up to which version, exactly?--> the "correct" answer (as indicated by the score received after the exam) is that holding an Everstone will prevent an {{cat|Pokémon that evolve by Evolution stone|eligible Pokémon}} from evolving using its corresponding stone, even though this has not been an effect of the Everstone since [[Generation IV]]. This was changed in an update, <!--Which one?--> changing the correct answer to "Yes, it will [evolve]."
