Real Enamel and silver fan earrings

This lovely enameled (real nor fake) double fan earrings have a movement to them when worn. I believe they are sterling because that is how I was of this quality are usually made but I did not see a 925 on them. They tarnish and are cleaned the same as silver but I'm not positive. The silver and black front is real enamel though. Not that junk that they try to pass as enamel on modern jewelry. Enjoy!
