This long black and gold necklace is adjustable, and can be worn at 31.0″ or 34.0″. The pendant piece is 2.3/8″ by 1/8″. Materials: 14k gold-fill or rose gold-fill (14k rose gold over brass core/no nickel) and oxidized sterling silver. 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 handmade in our Upstate New York production studio.
