Description

A brief review of structure and formation of pearls is given from the viewpoint of biomineralogy. Pearls are a gem produced by the metabolism of molluscs and are composed of nacreous layer containing more than 90% of calcium carbonate and about 5% of protein. The outer epithelial cells of the mantle piece, which are transplanted into the gonad or mantle tissue of another individual of the same species together with a pearl nucleus or without the nucleus, regenerat a pearl sac consisting of a single layer of cells and secrete inside the sac. Pearl mineral, tabular crystal of aragonite, grows alternatively with protein sheet in the secretion to form the laminar structure of nacreous layer which possesses a characteristic pearly iridescence. The mineralization of pearl and chemical composition of secretion and pearls are explained in this review.
