Sputnik style stud ball earrings 22k gold vermeil on stainless steel French made

Very fun sputnik style earrings perfect for mid century design nerds! Cannot remember the designers name unfortunately. I remember she was a French designer and I bought them from net-a-porter maybe ten years ago? One of the backing has been replaced, most of the gold vermeil has worn off mostly what is left is on the bottoms, accurate to the pictures. I was going through a gold phase so I do remember the gold is 21 to 22 karat.
