This round upper side ring is designed to be worn above the knuckle, or on your pinky finger. Your size in our upper side rings will typically be half your standard ring size. If your normal ring size is between a 4.5 and a 6.0, we recommend a size SMALL. For sizes 6.5 to 7.0, we recommend a size MEDIUM. For sizes 7.5 to 9.0, we recommend a size LARGE. Material: 14k gold-fill (14k gold over brass core/no nickel), sterling silver (.925) or 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 ring is designed in San Francisco and handmade in our Upstate New York production studio.
