Rainbow moonstone is a term sometimes used to describe fine colorless, transparent labradorite that displays a rainbow-colored iridescence. Internally repeating feldspar layers scatter the light that enters the stone creating a mystical blue glow that reminds one of moonbeams known as adularescence.
