1970s brutalist clip on earrings

1970s brutalist clip on earrings. These beauties are just shy of 3" long and every inch is amazing! Brutalist and modernist jewelry are truly the pillars of 70s accessories, don't you think? While most brutalist jewelry is made of copper, these are throwing me a bit- they don't quite have the copper feel, and therefore I am saying they are metal, just an f.y.i Era: circa 1970s Label: unmarked fabric: metal Condition: great vintage condition with minimal wear measures approx. 3" in length
