Answer 2

Pearls are hard, organic objects - the natural formation of a secretion called nacre that is produced by certain mollusks, primarily oysters. The process begins when epithelial cells come dislodged from the mantle tissue of the mollusk. Epthelial cells are the cells responsible for nacre deposition to the underside of a molluks' valve. When these cells become dislodged, they continue depositing nacre, eventually forming a natural pearl.

Often this is process caused by a parasite burrowing through the shell and mantle into the body of the mollusk. It may also happen when damage occurs to the outside of the shell. Contrary to what most think, a grain of sand is never the reason a pearl grows.

Cultured pearls are formed by inserting a round bead made of freshwater mother of pearl into the gonad of a marine mollusk, along with a small piece of donor mantle tissue. The donor mantle tissue contains epithelial cells which grow into a pearl sac and produce nacre.

Freshwater pearls are cultured by simply inserting a piece of donor mantle tissue into the host mantle of a freshwater mussel.
