Vintage Marcasite and Cultured Pearl Fan-Shaped Clip-On Earrings

This is a pair of vintage clip-on earrings featuring a decorative fan or scalloped shell motif. Each earring is crafted from what appears to be sterling silver or a high-quality silver-toned base metal, heavily encrusted with rose-cut marcasite stones that provide a metallic, glittery luster. At the base of each fan sits a single round cultured pearl or high-quality glass faux pearl with a creamy white nacre. The design is indicative of the Art Deco revival style, likely dating from the mid-20th century (circa 1940s-1960s). The earrings utilize a paddle-back clip mechanism for unpierced ears. In terms of condition, there is a visible dark patina and oxidation consistent with age, particularly in the recessed areas of the metalwork which helps the marcasites pop. One earring appears to be missing at least one small marcasite stone in the upper left quadrant. The pearls show a healthy matte glow, though some minor surface wear may be present upon closer inspection. The overall craftsmanship is detailed with milgrain edging around the stone settings, suggesting a higher level of decorative jewelry production from the era.
