"Adularescence is the optical phenomenon that causes the extraordinary glow on the surface of moonstone. The light moves across the stone much like moonlight would glide across a large body of calm water. This happens when light reflects off of the thin layers of different feldspar minerals within moonstone. The layers act as a diffuser, softening the light and allowing it to bounce around the stone."
