iridescence , exhibition of rainbowlike colors on a surface. It usually results from interference when light composed of different wavelengths is reflected from the superficial layers of organic or inorganic substances, e.g., minerals, mother-of-pearl, and the feathers of birds. Iridescence greatly enhances the value of certain gems.

iridescence A physical phenomenon in which fine colours are produced on a surface by the interference of light that is reflected from both the front and back of a thin film.
