Materials: 14k 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 rings were selected for our Ring Bar Happy Hour
event and are handmade in our Upstate New York production studio.
