Nacre: “Mother of pearl” is composed of hexagonal platelets of calcium carbonite (CaCO3) arranged in a continuous parallel lamina. These layers are separated by sheets of organic matrix. This mixture of brittle platelets and the thin layers of elastic biopolymers makes the material strong and resilient. Strength and resilience are also likely to be due to adhesion by the "brickwork" arrangement of the platelets, which inhibits transverse crack propagation.
Nacre appears iridescent because the thickness of the aragonite platelets is comparable to the wavelength of visible light. This results in constructive and destructive interference of different wavelengths of light, resulting in different colors of light being reflected at different viewing angles.
