Pearls are classic and charming options. Result of a natural reaction of the molluscs, to receive a foreign body in your interior, have a defense system that creates a thin layer of tissue that protects the viscera of the oyster. This substance secreted by the mantle is called mother-of-Pearl, a composition of 90% of a limestone material–the aragonite (CaCO3), 6% organic material (conqueolina, the main component of the outside of the shell) and 4% water.
This maturation process takes on average 3 years and only happens in only one every 10,000 oysters. The colors of pearls can change according to the substances present in the water.
Today, much of the pearls are cultivated since natural have become increasingly rare. Pearl cultivation is done in fresh water, the difference is that a synthetic core is inserted into Oyster for the process of defence and, consequently, the Pearl production.
