This black and gold interlocking necklace comes in two versions: one with rose gold pendant and chain, the other with a gold pendant and chain. The pendant measures 1/2” x 3/4”. The chain is adjustable and can be worn at 17.1/2″ and 19.0″. 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. This necklace is designed in San Francisco and handmade in our Upstate New York production studio.
