The Ramos Fizz Set is made up of five rings including one gold multi-line ring (a sneak peek from our first-ever Design Lab), two thin gold, one thin silver, and one thick gold band. This stack is available in our signature round and square shapes. 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.
