Heavy Modernist Copper Hinged Choker

I don't expect this one to last long. A very cool modernist, minimalist, heavy thick solid copper round wire choker. Center features a knot of copper, each side is drilled and pin hinged with great craftsmanship. The chain is a dark patina copper with a hook closure and a round end piece stopper. Could not find a signature but this is a designer artist made piece, very high quality. Meausurements: Width at center: 1 inch Length Can be as small as 8.5 inches or as long as 17.5 inches. Center Copper Pieces measure total of 8 inches. Chain to Right: 3.5 inches Chain to Left: 6 inches
