Rio Carnival Sunglasses / Eyeglasses Necklace. Flamboyant and ready for any festivities, this eyeglass necklace is decked out with jewel tone faceted crystals, gold tone beads, and jewel tone acrylic rondelle beads with encrusted crystals. Talk about a statement piece, this necklace measures 29 inches long with adjustable stretch ends to fit most frames. I recommend wearing this lavish beauty with larger frames for the focal beads size and this glasses necklace is slightly heavier than most that I make. PairsPerfectly with whenever you want to shine!
