How Do Oysters Make Pearls?

The video explains the origin and formation of pearls, which are used in jewelry. Pearls form when an irritant enters an oyster, prompting it to secrete layers of nacre around the irritant, creating a pearl. While many bivalves can produce pearls, oysters are particularly adept. The process involves the formation of a pearl sac and the secretion of nacre, primarily composed of aragonite. Cultured pearls are created by humans implanting tissue or beads into oysters to stimulate pearl formation.
