In the world of astronomy, a nova is a star that suddenly releases a huge burst of energy, temporarily becoming extraordinarily bright. The Nova Set is made up of four rings including one Aries Channel Band, one 7mm Wide Silver Densa Band, one 2.5mm Wide Gold Band, and one Thin Oxidized Stacking 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-fill (14k gold over a brass core/no nickel), sterling silver (.925), and oxidized sterling silver. All materials are hypoallergenic. This original stack creation was originally introduced as The Sazerac Set during the Ring Bar Happy Hour on IG Stories, and is handmade in our Upstate New York production studio.
