Natural pearls come in many shapes, however perfectly round ones are very rare. They are made up of calcium carbonate and conchiolin and are formed when a microscopic intruder or parasite enters a mollusk and settles inside the shell. The mollusk is irritated by the intruder and secrets the conchiolin/calcium carbonate repeatedly until a pearl is formed. Cultured pearls are formed when a tiny of mantle tissue from a donar shell is transplanted into a recipient shell, which causes a pearl sac to form. Such pearls can be produced using freshwater or seawater shells. They also go by the following names: Akoya, white or golden South sea, and black Tahitian.
Pearls are found in oysters. A pearl is developed when a grain of sand enters the oyster and its defense mechanism starts to wrap the sand in shell.
