These black and gold cinq earrings measure 2.1/4" x 1/2" at their widest point. Materials: 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 were designed in San Francisco and are handmade in our Upstate New York production studio.
