Vintage 925 sterling silver Modernist Brutalist Southwestern turquoise ring

One of a kind vintage handmade ring. Modernist Brutalist Mid-Century Modern style. Looks like a coiled snake. With natural blue turquoise stone of good quality. In excellent condition. Size 8.5, but may fit size 8 better due to its width. Not adjustable, the snake's tale is soldered to the band of the ring. Not stamped (or the stamp is no longer visible), but professionally tested as 925 sterling silver.
