The pendant on this black & gold inflecto necklace measures 5.1/2″ by 1/16″. The chain is adjustable and can be worn at 20.0″ or 22.0″. Materials: 14k gold-fill (14k over brass – 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 was designed in San Francisco and is handmade in our Upstate New York production studio.
