Vintage Copper cuff and earrings, Renoir (?)

Striking vintage Copper cuff bracelet with matching clip earrings. I cannot find a stamp/ makers mark but they resemble Renoir Fashion Jewelry, from many decades ago. The prior owner was an avid collector. I will date these to at least 1980s, if not earlier. They are copper and have a bold modernist design. I I do consider reasonable bundle discounts and offers. I also cross post most listings. Thanks for viewing.
