Vintage Circular Clip-On Earring

This item is a single, circular clip-on earring, viewed from the reverse side against a dark, textured background. The earring measures approximately 1 to 1.5 inches in diameter and features a flat back made of an opaque, off-white or cream-toned synthetic material, likely plastic, Lucite, or early resin. Centered on the back is a gold-toned metal tension clip-on mechanism, characteristic of mid-20th-century costume jewelry styles from the 1960s to 1980s. The metal appears to be a polished gold-plated finish, showing minor surface oxidation and light scratches consistent with age and previous wear. The cream-colored base is smooth with a matte-to-satin finish and appears to be in relatively good condition, though there are subtle visible scuffs near the edges. No prominent maker's marks or signatures are visible on the clip or the back plate, which is common for mass-marketed boutique costume jewelry of the era. The construction suggests a modest level of craftsmanship, typical of everyday fashion accessories designed for comfort without the need for ear piercings. Detailed examination shows the circular edge is clean, suggesting either a simple geometric disc design or perhaps a front-facing ornamental piece that is encapsulated by this backing.

Based on my direct examination of the provided imagery, this item is a single mid-to-late 20th-century costume jewelry clip-on earring. The construction—featuring a cream-toned thermoplastic or resin base paired with a standard gold-plated tension clip—is indicative of mass-marketed boutique jewelry from the 1960s or 1970s. The condition is fair to good, with visible oxidation on the metal clip and surface scuffing on the resin backing consistent with moderate use. The absence of a maker’s mark (e.g., Trifari, Monet, or Napier) suggests this was an unbranded fashion accessory. The market for single, unsigned vintage earrings is limited, as they are typically sold for 'repurposing' or as replacement parts unless part of a complete pair. Comparables for unsigned plastic and gold-tone earrings in the current secondary market (platforms like Etsy or eBay) consistently fall under the $25 threshold. The rarity is low, as these materials were produced in high volume during the era. Several limitations exist in this digital appraisal. I cannot verify the specific chemical composition of the backing (e.g., Bakelite vs. Lucite vs. Modern Resin) without a Simichrome test or thermal spot test. Furthermore, I cannot assess the tension strength of the clip or the presence of hallmark etchings that might be obscured by glare. A definitive valuation would require an in-person physical examination to rule out higher-end designer signatures and to confirm the base metal composition via acid testing. Provenance documentation regarding the original retail source would also assist in refining this estimate.
