"Galaxy" is as big and bright as our universe itself!  The beads include sky blue opalite beads that glow with a pinkish blue light, blue zircon quartz nuggets and rhondelles, and 8mm bicone aqua beads.  The necklace is 18 inches in long, and the toggle clasp and lever-back earwires are sterling silver.  Nothing will out-shine this necklace!
