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.

Based on my visual examination of these fan-shaped clip-on earrings, I have identified them as mid-20th-century Art Deco Revival pieces, likely dating from the 1940s to early 1960s. The craftsmanship features classic milgrain detailing and hand-set rose-cut marcasites, typical of quality costume or semi-fine jewelry of the era. The condition is fair, with a desirable natural patina that highlights the geometric metalwork. However, the value is slightly suppressed by the absence of at least one marcasite stone and minor surface wear on the pearls' nacre. Market demand for marcasite remains steady among vintage enthusiasts, though the clip-on mechanism and commonality of 'fan' motifs place this in a more accessible price bracket. Without a physical inspection, I cannot definitively confirm if the metal is .925 sterling silver or if the pearls are cultured rather than faux. Limitations of this photo-based appraisal include the inability to check for maker's marks on the paddle-backs or perform a 'tooth test' or loupe inspection for nacre quality. To certify the higher end of this value range, an in-person acid test for silver content and a microscopic examination of the stone settings would be required. Proper provenance or a original jeweler's box would also enhance the final valuation.
