This Happy Hour Mix-Up is made up of 5 rings including 1 thick gold round, 1 thin silver and gold square, 1 3mm silver round, 1 thick rose gold square and 1 thick silver round ring. We've included photos of this set paired with our Blonde Ale band to show just one example of how to level up your stack. This listing is for the Mix-Up #12 set only. Special note: Because of the width of our stack ring sets, 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 and rose 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 Hour on IG Stories, and is handmade in our Upstate New York production studio.
