This long black and gold rounded square necklace comes in two variations: one with a gold and black pendant on a gold chain, and the other with a rose gold and black pendant on a rose gold chain. The pendant measures 1.3/8″ by 1.3/8″. The chain measures 31.0”. 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 was designed in San Francisco and is handmade in our Upstate New York production studio.
