Inspired by the night sky this star signet pendant necklace measures 20mm in diameter. It includes a beaded tight loop cable chain measuring 34" long and has a balloon clasp and "So Pretty" logo charm attached. It is made of 18K heavy gold plating (2.5-3 microns thick) onto solid sterling silver. This is the perfect everyday piece and is wonderful worn layered with a shorter necklace. Each gemstone is genuine and unique so you may receive a stone that is slightly different in color.
