This mixed metal ring consists of three different gauged metals. The stack includes: 1 thick silver band, 2 thin gold bands and 2 thin silver bands. This ring is available in sizes 4.0 – 11.5, including all half sizes. Special note: because of the wideness of the stack rings, it is recommended to buy a stack that is 1/2 size larger than your normal ring size. Of course, if you order a ring and the fit is not quite right, we are more than happy to exchange it for the correct size. Materials: sterling silver (.925) and 14k gold-fill (14k gold over a brass core/no nickel). All materials are hypoallergenic. This ring is handmade in our California and New York production studios.
