The Tundra earrings are impressive and sculptural, yet leafy and light. Their refined structure and the golden glow of bronze beckon to come and look closer. Stud fastening, silver stud and back. You can make the earrings even more impressive by attaching to them dangling extension pieces sold separately. The dangling parts have a small silver hook that is slipped through the tiny loop on the backside of the earrings. The fastening is secured with a small silicone stopper. Both the earrings and the extension pieces are mirror images of each other. The top and bottom of the right earring are marked with a circle for pairing and identification. There is no marking on the left earring. Also available in silver.
