Vintage Silver-Tone Enamel Drip or Stone Inlay Door Knocker Post Earrings

This lot contains a pair of vintage fashion earrings featuring a rectangular 'door knocker' or drop style design. The earrings are constructed from a silver-toned base metal, possibly brass or alloy with a rhodium or nickel plating. Each earring includes a central decorative panel with a mottled blue and grey finish, evocative of natural stones like dalmatian jasper or a granite-style drip enamel glaze. The metal frames exhibit a brushed or textured finish on the reverse side, a common mark of costume jewelry from the late 20th century, approximately the 1980s or 1990s. The earrings utilize post-and-butterfly clutch closures. Condition-wise, the plating appears mostly intact with minor surface scratches and slight oxidation near the hinges. No clear maker's marks are visible on the reverse, suggesting mass-market production. One earring is flipped to show the textured metallic back, while the other displays the smooth, high-gloss decorative inlay. The overall craftsmanship is consistent with mid-range costume jewelry designed for everyday wear.
