Evolutionary gem

Evolutionary gems are items introduced in Pokémon Twilight. They are small, altered fragments of the evolution stones that can be held by a Pokémon to power up moves and induce evolution. They also power up the move Eon Pulse.

Effect
Each of the gems raises the power of the holder's moves of a specific type by 30%. It also has a 50% chance of causing the Pokémon to evolve upon leveling up if it would normally evolve using the corresponding evolution stone. Eevee has a 100% chance of evolving upon leveling up while holding a gem; all of its evolutions can be obtained via gems, even though only three of the forms are obtained through the use of a stone. They also raise the power of Eon Pulse to 60 and cause it to inflict various status conditions.
