Our moonstone bracelet is handmade in sterling silver with a 12mm round natural moonstone gemstone set into a fleur de lis setting with blue flashes of color. The center stone is adorned with faceted rondelle shaped moonstones and double circle links on each side. We added a 1 inch extender so you can adjust the length. The setting has an antiques silver look and the center moonstone is cabochon cut. Stones are wrapped onto our sterling silver curb chain that closes with a spring clasp. 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. Materials: Moonstone 12mm round cabochon cut gemstone and 4-5mm faceted rondelles All metal components are 925 sterling silver If you have any questions just click "message seller" on our homepage.
