This is a bump up to the thin stacker ring because it has a 6mm sterling bezel and birthstone instead of 4mm. It is more dramatic and when paired with 4mm and different colored stone it creates a very cool effect. It’s available in a variety of band styles: plain (square or round), textured, stamped, beaded, or twisted. Once you purchase, Judi will email you for exact specifications and size. Allow 2 weeks or let Judi know you need sooner. This price is only for one 6mm ring (picture may show it with other stackers/spacers).
