Pearl is produced by an oyster to protect itself from something that got inside its shell. It secretes nacre, which becomes pearl. Cultured pearls are made by placing a "seed" inside of the oyster shell, and letting the oyster work. Over time, the oyster will deposit nacre onto the seed, forming a pearl.

No, pearls do not form from raindrops. Pearls are formed inside oysters when an irritant (such as a piece of sand or debris) becomes trapped inside the oyster. The oyster then secretes layers of nacre around the irritant to form a pearl over time.

A mollusk is a shelled sea creature that has a muscle in the inside like a clam or oyster. The name comes from its soft inside.
A natural pearl inside an oyster can take anywhere from 1 to 3 years to form. The process begins when an irritant such as a grain of sand or debris enters the oyster and the oyster secretes nacre to coat the irritant, forming a pearl over time.
