Everstone

The Everstone is an item introduced in Generation II.
==Effect==
===In Evolution===
When held by a Pokémon, it prevents the Pokémon from evolving via leveling and trading. It does not prevent evolution by directly using items like Evolution Stones.
===In Breeding===
If the mother (or Ditto) is holding an Everstone, the baby has a 50% chance of inheriting the mother's Nature.
Ditto always acts as the "mother" in a breeding match-up, so in Emerald, a female breeding with a Ditto does not have a better chance of passing down Natures to its offspring; the Ditto does. In Generation IV, in Diamond, Pearl, and Platinum, inheriting Natures remains the same as in Emerald. However, in the Johto remakes, HeartGold and SoulSilver, inheriting Nature was changed a little. Whichever Pokémon is holding an Everstone will pass down its Nature, regardless of gender, or whether it is breeding with a Ditto. Another minor change that is present in all Generation IV games, is that the passing on of Natures via an Everstone will not work if the Pokémon are from different real-world countries (e.g. Argentina and Spain). This restriction is lifted in Generation V.
In Black 2 and White 2 the odds of passing down the Nature of the parent holding an Everstone is now 100%. If both parents are holding an Everstone, the odds are 50/50 between each of the parents' Natures.
If a regional variant is holding an Everstone while breeding with the opposite genders or a Ditto, it will produce the original variant of the Pokémon.
