Marcasite-style drop earrings in a vintage silver-tone aesthetic

This pair of earrings appears to be constructed in a style consistent with vintage marcasite jewelry. Each earring features a floral-shaped stud leading to a larger, circular drop pendant with a radial, wheel-like pattern. The metal exhibits a dark, patinated silver-tone finish with numerous small, metallic-grey stones set throughout, which are characteristic of marcasite (iron pyrite) or faceted glass imitations. The construction includes visible articulated links between the stud and the drop, allowing for movement. No hallmarks or maker's marks are legible in the provided image, so the material composition—whether sterling silver, silver-plated, or a base metal alloy—cannot be determined without physical testing. Stylistically, the ornate, geometric detailing is consistent with Art Deco revival or mid-20th-century costume jewelry. Visible condition includes some tarnishing and darkening of the metal recesses, which is typical for this aesthetic. One earring's post appears slightly bent, but they otherwise seem to be in fair condition. The identification remains a hypothesis based on visual cues as no branding is present.

Based on the provided image, I have examined this pair of marcasite-style drop earrings. I can clearly see the ornate Art Deco revival styling, the articulated radial drops, and the patinated silver-tone finish set with numerous small faceted stones. However, because there are no legible hallmarks or maker's marks visible in the photo, I cannot determine the exact metal composition or stone material. Physical testing would be required to establish whether these are crafted from sterling silver with genuine iron pyrite (marcasite) or if they are a base metal alloy with faceted glass imitations. The visible condition shows typical tarnishing and a slightly bent post, which modestly impacts the valuation. The working assumption is that these are mid-20th-century vintage costume earrings. The market for unsigned vintage marcasite-style jewelry is modest but steady, primarily appealing to casual collectors of vintage aesthetics. If physical inspection indicates they are indeed sterling silver with genuine marcasite, the value would likely sit at the higher end of the provided estimate. Conversely, if they turn out to be modern base-metal reproductions or contemporary costume pieces, the secondary market value would be negligible, likely under $15. To firmly establish the materials, age, and any potential maker, an in-person examination and standard metallurgical testing would be necessary.
