Moonstone is a type of mineral belonging to the feldspar group. Stones in the feldspar group include labradorite, sunstone, and amazonite, and they are so diverse that they don't seem to be from the same family. Moonstone is mainly 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." This is a very beautiful moonstone bracelet with a chic, off-white base color and a fantastic schiller. Because the base color is dark, the white shimmering schiller is very visible. The beads are a good size, so you can fully enjoy the charm and beauty of the moonstone. Size: 12-12.4mm x 17 beads Inner Diameter: 17cm and up Origin: Sri Lanka
