Hint: A pearl is a gleaming, hard object formed within the soft tissue of a living shelled mollusk or another animal, such as fossil conulariids. A pearl, like a mollusk's shell, is made of calcium carbonate in minute crystalline form that has been deposited in concentric layers.

Complete answer:
A cultured pearl is a genuine pearl created by an oyster or mollusk with the assistance of humans. Freshwater and saltwater pearls are the two main types of cultured pearls. Pearl farmers physically insert an irritant, such as a shell bead nucleus, inside the soft tissue of the oyster during the pearling process. To begin, cultured pearls require the assistance of pearl farmers.

• Freshwater pearls are produced by mussels that live in rivers and lakes.
• Saltwater pearls are produced by oysters in oceans and come from Thailand, Australia, Indonesia, and Tahiti.
• Freshwater pearls are less lustrous and glossy than saltwater pearls.

A pearl is formed when the mantle tissue of a mollusk shell bivalve or gastropod is damaged by a parasite, a fish attack, or another event that damages the external fragile rim of the shell. In response, the mollusk's mantle tissue secretes nacre into the pearl sac, a cyst formed during the healing process. In terms of chemistry, this is calcium carbonate and a fibrous protein known as conchiolin.

Note: The most valuable pearls are found naturally in the wild, but they are extremely rare. These wild pearls are known as natural pearls. The majority of pearls sold today are cultured or farmed pearls from pearl oysters and freshwater mussels.
