Did eviolite is implemented?

 

eviolite item:

 

Eviolite is a held item introduced in Generation V. When the player gives an Eviolite to a Pokémon that is capable to evolve, it raises the Defense and Sp. Def of the Pokémon's stats by 50%. Even though its Japanese translation is Evolution Stone, it does not evolve any Pokémon. It is obtainable in Castelia City in the topmost building in the road above the park in the middle of Castelia City. Have at least 40 Pokédex entries and speak to the scientist to obtain the Eviolite.

You can obtain an Eviolite as a reward for having Dragon Membership, or from completing Hiker Jiwan's medicine quest in Hoenn.
