Gorgeous Vintage Silver Hoop Earrings

I was working against the light, and I couldn't see how fuzzy the pics came out. I will have to try to take better photos another day. These are absolutely gorgeous silver stampwork hoop earrings. There are no hallmarks, but they are of high quality. Either Sterling Silver, or stainless steel. They have been stamped on either side with a beautiful, unusual swirling design. They seem to have been gold-plated at some time, as there is evidence of a subtle yellow gold overtone here and there, but it has faded almost completely. These are in great overall vintage condition. So unique and classy. They are not heavy at all, and are about 4 cm in length.
