In battle

If held by a Diancie, allows it to Mega Evolve into Mega Diancie if its Trainer has a Key Stone. Each Trainer can only Mega Evolve one Pokémon per battle.

Unaffected by item negating effects (such as Embargo and Klutz). Item manipulating effects (such as Trick and Fling) cannot give Diancie a Diancite or remove a Diancite from Diancie.

Outside of battle

If held by a Diancie, allows it to Mega Evolve into Mega Diancie when it performs a Spectacular Talent during a Pokémon Contest Spectacular while its Trainer has a Key Stone. Diancie will remain a Mega Diancie until the Talent Round ends.
