Stones in the feldspar group include labradorite, sunstone, and amazonite, and they are so diverse that you wouldn't think they were in the same group. Moonstone mainly consists of orthoclase and includes albite. The layers of these two types of feldspar overlap, causing internal reflection and interference of light, resulting in a fantastic light effect called "schiller (sheen)". This light is the most characteristic charm of moonstone and is thought to have inspired the image that gave it its name. Commonly known moonstones are often milky white or translucent, but there are also various colors such as orange, pink, yellow, green, grayish green, gray, brown, and tan. Moonstone is the birthstone for June. In the past, this stone was believed to be the crystallization of the moon's glow and was revered as an incarnation of the moon's magic. Ancient Indians revered moonstone as a "sacred stone" and wore it as an amulet. It was thought to grant truth and protect from danger, like the moonlight illuminating a night path. Note that moonstone is a trade name, and the formal mineral name is white labradorite. Item No. BG5708-105
