The Eviolite (Japanese: しんかのきせきEvolution Stone) is a type of held item introduced in Generation V. It boosts the Defense and Special Defense of a Pokémon that holds it if the holder is not fully evolved.

It affects male Combee and Salandit (despite them not being able to evolve while females can).
It still affects Pokémon that can evolve in the current game, even if it is not currently possible to meet the requirements for their evolution. In Pokémon Sword and Shield, Galarian was affected by the Eviolite even before the Galarica Cuff or Galarica Wreath were available. In Pokémon Scarlet and Violet, it affects Ursaring, Stantler, and HisuianQwilfish, despite their evolution methods currently being unachievable. In addition, it also affects Dipplin, which currently has no way to evolve
If held by a transformed Pokémon, the boost is based on its original species, not the species it is transformed into.
Eviolite was introduced as a Pokémon Tool card in the Pokémon Trading Card Game during the English Black & White Series (the Japanese BW Era) in the Noble Victories expansion. When this Trainer card is attached to a Basic Pokémon, any damage done to this Pokémon by attacks is reduced by 20, after applying Weakness and Resistance.
Trivia
Eviolite is not a dictionary word. Instead, the name may be derived from evolution and previous, and the -ite suffix found in the names of many minerals.
Eviolite's Japanese name contains a pun; しんかのきせき Shinka no Kiseki can also be taken to mean "Miracle of Evolution".
