Red Faceted Clip-on Earring

This item is a singular vintage-style clip-on earring featuring a vibrant, opaque red decorative element. The primary aesthetic feature is a large, circular cabochon or dome that has been multifaceted with geometric, diamond-shaped cuts. These facets are designed to catch and reflect light, giving the matte-looking material a distinct shine. Based on the uniform color and internal reflection qualities, the material appears to be a high-quality resin, lucite, or possibly a glass paste, characteristic of mid-20th-century costume jewelry. The diameter is approximately 1.5 to 2 centimeters. The backing consists of a silver-toned metal clip mechanism, likely composed of a base metal or stainless steel, which shows some minor oxidation consistent with age. There are no visible maker's marks or signatures on the surface of the red component or the visible portion of the clip. The condition is overall good, though there is slight surface wear and micro-scratching on the red facets near the apex of the dome. The style is reminiscent of the bold 'button' earrings popular during the 1960s to 1980s. The craftsmanship is standard for mass-produced costume jewelry of that era, focused on bold color saturation and ergonomic clip design for non-pierced ears.

I have examined the provided description and visual characteristics of this single red faceted clip-on earring. The piece exhibits the classic 'button' profile prevalent in mass-market costume jewelry from the 1970s through the late 1980s. The material is consistent with a molded resin or lucite, displaying the sharp geometric faceting typical of mid-range production. The condition is fair to good, though the presence of micro-scratching on the apex and oxidation on the silver-toned clip mechanism indicates a history of wear. Market demand for unsigned, single costume earrings is significantly lower than for matched pairs or signed designer pieces (such as Miriam Haskell or Trifari). This item is categorized as a high-volume, mass-produced accessory. Current market comparables for individual 'orphaned' earrings of this type typically sell within the $5 to $12 range, often purchased for use in craft 'upcycling' or as replacement parts. Its value is limited by its lack of a maker's mark and the fact that it is an incomplete set. Factors that would positively impact value include finding its matching pair or discovering a signature on the inside of the clip hinge. Limitations of this Digital Appraisal: This evaluation is based on visual data alone. A physical inspection is necessary to determine the exact metal composition (to rule out sterling silver) and to verify if the red element is glass or plastic via a thermal conductivity test. Full authentication of the era would require examining the tension and patent marks of the clip mechanism. To confirm provenance, original packaging or a sales receipt would be required.
