Moonstone is a gem variety of feldspar, known for its distinctive adularescence, a milky, bluish-white light that seems to float across the stone's surface. This phenomenon is caused by the way light interacts with the mineral's layered structure, which is composed of alternating layers of albite and orthoclase.Moonstones can be found in various colors, including colorless, white, peach, gray, and even rainbow hues (rainbow moonstone).
