The Iridescence of Mother of Pearl

The fascinating, rainbow-colored shine of mother-of-pearl is due to the fact that mother-of-pearl is made up of several layers of aragonite and conchyne, one on top of the other. Each of these individual layers allows some of the light rays to pass through and some to be reflected. The interference, ie the superposition of the incoming and reflected light, creates the colorful shades that are characteristic of mother-of-pearl. The strength of this optical effect depends on the angle of the observer. If the mother-of-pearl is moved, a lively and colorful shimmer can be observed.
