Brutalist Copper and Mixed Metal Studio Cuff with Red Cabochon is a great mid-century piece. The unusual shape and textures on this piece give it a definite one of a kind dimension. It has a hinged back, and closed with a hook that goes over the high set bezeled cabochon. It will only fit a very small wrist, measuring approximately 6 1/4 inches in diameter. It is 1 7/8 at the widest point. A great looking piece of art jewelry for your collection.
