Pearls are harvested from Oysters.

Pearls are natural or cultured gems produced by certain molluscs, most commonly bivalves like oysters (specifically pearl oysters). They form when an irritant, such as a parasite or a piece of shell, enters the mollusc and is covered by layers of nacre (mother-of-pearl) as a defense mechanism. While other molluscs can produce calcareous concretions, true pearls of commercial value are primarily associated with oysters and sometimes mussels. Prawns are crustaceans, Pila is a gastropod snail, and Tuna is a fish; none of these produce pearls.

Pearl cultivation (pearl farming) is a major industry, involving the deliberate insertion of a nucleus or irritant into pearl oysters to stimulate pearl formation. Different types of oysters produce different types of pearls, such as Akoya, South Sea, and Tahitian pearls.
