A flat earcuff made out of mother of pearl. Engraved logo.

Mother Of Pearl, also known as nacre, an organic-inorganic composite material produced by some molluscs as an inner shell layer. It is resilient, strong and iridescent. The outer layer of cultured pearls and the inside layer of the shell of pearl oysters and freshwater pearl mussels are made of nacre. It is composed of hexagonal platelets of aragonite whose thickness is close to the wavelength of visible light, which causes its iridescent appearance. Their structure interfere constructively and destructively with different wavelengths of light depending on different angles of viewing.
