Nib 7 piece boho ring set, above knuckle silver

New in sealed bag, I only took them out to check for flaws. All 7 rings can go above and below your knuckles creating the cool looks you see in the pics. The ring sizes are posted in 3rd pic. I have extremely large hands so this doesn't work well on me. But average and smaller hands should be fine. Purple crystal as in photos! Found
