Vintage SIGNED Trifari Black Enamel & Silver Tone Clip On Earrings

A pair of vintage Trifari clip on earrings featuring black enamel set in silver tone metal. I believe these date from the 1980s based on the raised "Trifari TM" stamp. These are in very good pre-owned/vintage condition with just a little chipping of the plating on the back where the earring closes. Measurements: approximately 1 inch in diameter.
