These black and gold triangle pull-through earrings measure 1.1/4″ long by 1/2″ at their widest point. Material: 14k gold or rose gold-fill (14k gold over brass core/no nickel) and oxidized sterling silver (.925). All materials are hypoallergenic. The black (oxidized) components of our jewelry will wear over time and eventually achieve a beautiful antique-like finish. These earrings are designed in San Francisco and handmade in our Upstate New York production studio.
