Shine as bright as the stars when wearing the iridescent sparkle of the Sterling Silver Swarovski Elements Crystal Aurora Borealis Star Pendant Necklace. A genuine Swarovski Elements crystal is presented by a 925 sterling silver bail at the base of an included 18-inch box chain. The star shape reveals a magnificent faceted finish that picks up a rainbow variety of colors in all light. This pendant is secured in place as the necklace is finished with a spring-ring clasp.
