Pearls are primarily created by bivalve mollusks, often
from the oyster family. In nature, irritants such as a small pebble or even a grain of sand get trapped
in the oyster's shell and the creatures natural reaction is to build up beautiful layers of "nacre" which is
primarily comprised of calcium carbonate and conchiolin. These substances bind the
microcrystals around the irritant concentrically.
Pearls are created in nature, but since the 20th
century, pearls have been cultured by human beings intentionally to produce beautiful salt water
and freshwater pearls. Although the process of how the mollusks create the pearls is essentially the

will result. Cultured pearls can be made in a variety of shapes as different types of starter
beads can be used to make that possible. Cultured pearls now make up approximately 90%
