Held by wild Pokémon in 3 places.
A rather large pearl that has a very nice silvery sheen. It can be sold to shops for a high price.
Every wild place a Pokémon that may hold Big Pearl turns up, best odds first. The odds are how often each of them appears there times how often it holds the item, added up for every one you can meet at the same time. Hold chances are from the game's files as of August 2026.
