Vintage silver filigree dangle earrings with iridescent gem

Gorgeous, feminine, and delicate silver filigree earrings with a small iridescent gem at the center. It has a little more of a rainbow sparkle to it than it shows in the pics! I'm not 100% sure what the metal of the drop is - it's very thin and lightweight. It could be silver, but I don't want to guarantee it. However, the hooks are stamped as silver, as shown. earrings measure about 1.5" long and 0.5" wide
