Sterling silver drop earrings with genuine Swarovski crystals and Moonstone beads. Moonstone is a variety of the feldspar-group mineral orthoclase. During formation, orthoclase and albite separate into alternating layers. When light falls between these thin layers it is scattered producing the phenomenon called adularescence. Adularescence is the light that appears to billow across a gem. These match perfectly with Semplice Caterina's Moonstone Bracelet. They're sure to get "glowing" compliments!
