This wire wrapped necklace is made with gold wire that will not tarnish. These clear beads are iridescent and will shift colors in the light(reminds me of sparklers on the 4th). This is necklace is 15.5 inches long + a 3 inch long extension chain, making the total length of the necklace 18.5 inches long. The lobster claw clasp and extension chain are both 14k gold filled.
