If you’re unsure when or how a Pokémon will evolve, this information is easy to find online. You can check the Pokémon’s page on a Pokémon resource site like Bulbapedia, for instance. [1] X Research source Note that select Pokémon will only evolve by using special items or by meeting special conditions. For example, Most Eevee evolutions require an evolutionary stone to evolve (Flareon, Vaporeon, Leafeon, Jolteon) while Espeon requires a certain level of friendship to be reached between 6 am-6 pm, and Umbreon requires friendship to be reached from 6 pm-6 am. Sylveon requires a soothe bell to be held while it reaches the correct level of friendship, and you must be in the appropriate location for Eevee to evolve into Glaceon.

More modern Pokémon games generally have fancier evolution screens than older games, but the general idea is the same for all games in the series.

Eventually, you will see “Huh? (name of Pokémon) stopped evolving!” or a similar message. At this point, the evolution is canceled. If your Pokémon gained a level, it will keep its level but will stay in the same form.

For Pokémon that evolve normally from leveling up, you’ll need to cancel every time the Pokémon gains a level.

Everstones are only in games from Generation II onward. [2] X Research source In other words, they do not appear in the original Pokémon Red/Blue/Yellow games.
