Vintage 1980s fan shape two-tone earrings

Vintage 1980s fan shape dangle earrings. These have a fan/shell shaped top, a silver ring, and a fan/shell shape bottom that dangles. Two toned gold and silver design. These are silver plated with post backs. A bit tarnished, but I will clean them before sending them out. Not marked sterling, so these are probably silver plate. 1.25 inches long .5 inches wide.
