Abstract

The marine pearls in nature are formed as a result of protective and defense mechanism when a foreign object enters between the shells of a pearl producing mollusc. The mantle epithelial layer in turn starts secreting a nacreous material which covers the foreign object with several layers of nacre, in the form of brick and mortar which is a composite material consisting of calcium carbonate present in the form of aragonite tablets and a proteinaceous organic matrix resulting in the formation of a lustrous pearl.
