Evolution Stones (commonly known as Elemental Stones) are crystals with the power of a certain element that instantly evolve certain Pokémon they are used on. There are currently nine different stones for evolving Pokémon.
- Fire, Water, and Thunder Stones evolve Pokémon of the corresponding Pokémon types, for example Vulpix, Staryu, and Pikachu, respectively.
- The Moon Stone evolves fairy-like Pokémon, like Clefairy, Nidorino, and Nidorina.
- Leaf Stones evolve Grass-types, such as Exeggcute and Weepinbell.
- The Sun Stone, introduced in Pokémon Gold and Silver, evolves the plant Pokémon Sunkern, Petilil and Gloom.
- Pokémon Diamond and Pearl added Shiny, Dusk, and Dawn Stones:
There are a handful of other stones related to evolution, although they are not considered Evolution Stones:
- The Everstone prevents the Pokémon that holds it from evolving.
- The Sun Shard and Moon Shard (found in Pokémon XD only) simulate the effects of Day and Night, which allows a happy Eevee to evolve into Espeon or Umbreon.
- When a Slowpoke or Poliwhirl holds the King's Rock and is traded, it will evolve into Slowking or Politoed, respectively.
- When a Happiny holds the Oval Stone and levels up, it will evolve into Chansey.
