All waterborne organisms living within shells, called mollusks, have the ability to produce Pearls. However, very few mollusks with single shells, called gastropods, do so. High quality Pearls are produced by the mollusk family called bivalves, which have two-part shells. But even amongst the bi-valve oysters the chances of producing a Pearl are a thousand to one.
 

The popular belief that a Pearl is formed as a result of a grain of sand entering a mollusks shell is false. The many layers of nacre, Mother Of Pearl, that form a Pearl are made when an organic irritant such as a parasite, or wayward food-particle become trapped within the mollusk, or if the mollusk is injured in some way.

Sensing the object the living organism within the mollusk secretes calcium carbonate, a derivative mineral of aragonite, and the binding protein conchiolin. This nacre, Mother Of Pearl, is the same substance that the animal uses to build its shell. The layers of calcium carbonate settle on the intruder and are interspersed by the conchiolin, which acts as a kind of organic glue binding the calcium crystals together. These substances combine and the regularity of the nacre (Mother Of Pearl) layers results in giving the Pearl what is called its luster.
