These tri-toned stick earrings measure 3.3/8″ long by 1/4″ at their widest point. Materials: 14k gold or rose gold-fill (14k gold over brass core/no nickel), sterling silver (.925), and oxidized sterling silver. 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 were designed in San Francisco and are handmade in our Upstate New York production studio.
