Hammered, irregular, wave-topped, every curve a little different because it's shaped by hand, not stamped from a die. It sits high and catches light unevenly across the hammer marks, which is rather the point. No clasp, no sizing. Slide it open, slide it on.
Why choose this one: if you want texture and a bit of movement rather than a clean line.
Sterling silver. Open-backed, adjustable to fit most fingers. Hammered finish.
