🐍 vintage sterling silver coiled snake ring OS

.925 sterling silver snake wrapped around the finger. Chapal Zenray 1980s. (See NF stamp in last pic). Beautiful and exquisitely detailed. Priced significantly lower than other comps I found online. Ruby hued eyes. Faceted marcasite stones throughout. Missing one (last pic). Approx size 6.5, but coil can be sized up and down. Body is slightly warped from resizing over the years, see pics.
