Pokémon evolutions by elemental stone
This is a list of Pokémon that evolve by using an elemental stone item. Generation 1 included the Fire Stone, Water Stone, Thunder Stone, Leaf Stone and Moon Stone. Generation 2 introduced the Sun Stone, while Generation 4 added the Shiny Stone, Dusk Stone, Dawn Stone and Oval Stone to the mix.
To evolve a Pokémon via stone, simply select the item to use in your bag, then select the Pokémon to apply it to - they will evolve straight away.
This information applies to any games that feature both Pokémon from the chain (and the stone), so for example in Generation 1 the Sun Stone doesn't exist, thus the evolution chain with Bellossom doesn't exist.
