About Moonstone: Moonstone is a natural gemstone in the feldspar family of minerals known for its blue flashes of color. The shimmering effect in the moonstone is called adularescence. Rainbow moonstone has a unique crystal structure that creates this optical phenomena by alternating layers of albite inclusions and layers of orthoclase. This creates a whitish-blue sheen of color as the light enters the stone and bounces back. Moonstone can be found in many places around the world, with the most popular deposits in India and Sri Lanka.
