Both natural and cultured pearls are assembled with several protective layers of nacre around the irritant (the core of the pearl).Composed primarily of aragonite and conchiolin, the pearl stone embodies the delicate balance of nature’s craftsmanship.

Another type of pearls is cultured pearls. They are produced, when pearls grow in farms by the involvement of human beings. In both types, a composition of Aragonite and Conchiolin is used for the formation of a pearl. Hence, calcium and protein play an important part in the production of pearls. The size, color, and shape of the pearls depend on the type of aragonite and conchiolin.

Aragonite, a crystalline form of calcium carbonate, constitutes the structural framework of pearls, providing strength and durability. Its intricate lattice structure lends pearls their iridescence, as light refracts and reflects off the myriad layers within. Conchiolin, on the other hand, acts as a binding agent, holding the aragonite crystals together and imparting flexibility to the pearl.
