Evolutionary Stones

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 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 and Gloom. Pokémon Diamond and Pearl added Shiny, Dusk, and Dawn Stones: Shiny Stones are used to evolve Togetic and Roselia, Dusk Stones are used to evolve Murkrow and Misdreavus, and Dawn Stones are used to evolve female Snorunt and male Kirlia.

There are a handful of other stones related to evolution. 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.
