Vintage Estate Pierced Drop Earrings. I believe this vintage pair to date to about the mid to late 1990s when the use of Czech buttons and vintage findings were all the rage. They feature beautiful amethyst crystal plaques with faceted edges and concave centers. The centers are embellished with enameled birds. They are beautifully styled with brass drops and faceted beads. The earrings have an overall measurement of two and five eighths by five eighths of an inch in diameter. Very nice condition with an aged patina.
