Our Glass of Bubbly set is made up of 2 rings including 1 thick gold round and 1 thick silver round. Here we've also included a photo of it paired with The Light Charcoal Shot to create a gorgeous tri-toned look. Special note: Because of the width of this stack ring set, it is recommended to buy a stack that is approximately a half to a full size larger than your normal ring size. Materials: 14k gold-fill (14k gold over a brass core/no nickel) and sterling silver (.925). All materials are hypoallergenic. This original stack creation was featured during the Ring Bar Happy Houron IG Stories, and is handmade in our Upstate New York production studio.
