Irridescence

This is an optical phenomenon in which the hue on the surface of the stone changes according to the angle from which the surface is viewed. A similar phenomenon may be seen on the surface of soap bubbles and on butterfly wings. The word is derived in part from the Greek word iris, meaning 'rainbow', from the goddess Iris, the personification of the rainbow in Greek mythology.
