Boho ring in silver and gold #647 I've heard some buyers calling these "spinner" or "fidget" rings because the outer gold tone bands spin around, and that the design became popular recently because some major designers were making them using precious metals. For my own style, I opted for a dab of Gorilla Glue and it spins and fidgets no more. Perfect for stacking, mixing and matching. Just the right size to have personality without being overwhelming or masculine! Note about the material: This ring is NOT 925 sterling. If I could find this in sterling, I'd buy it in a heartbeat! The manufacturer tells me that it is a stainless steel and zinc alloy that is designed to be durable and resist tarnish. I wear mine at least twice a week for the last six months and it still looks brand new. If you have any questions, or if you'd like additional pictures or measurements, just let me know.
