Art Deco-style gold-tone and black enamel triangular earrings

This pair of earrings, consistent with mid-to-late 20th-century costume jewelry, features a distinctive shield or soft-triangular silhouette. Each earring consists of a central inset of smooth, black resin or enamel that appears to have a slight domed curvature. Surrounding this central element is a gold-tone metal openwork border featuring a geometric lattice pattern, stylistically consistent with Art Deco revival designs common in the 1980s. The outer frame is polished, while the interior openwork adds visual complexity. No maker's marks or hallmarks are visible in the photograph, making identification based solely on visual aesthetics; without a view of the reverse, the fastening mechanism (pierced or clip-on) remains unverified. The surface appears to be in good vintage condition, exhibiting no obvious signs of metal pitting or significant enamel chipping, though minor surface scratches may be present upon closer physical inspection. The user-supplied context identifies these as 'Earrings,' which is supported by their size and paired nature. The craftsmanship appears to be of standard costume jewelry quality, utilizing cast metal and poured enamel techniques.

Based on my visual analysis of the provided image, these earrings appear to be unsigned costume jewelry consistent with the Art Deco Revival aesthetic of the 1980s. I can observe a gold-tone openwork border with a geometric lattice design surrounding a black domed inset, likely resin or enamel. From this photograph, I cannot verify the base metal composition, the specific material of the inset, or the type of fastening mechanism on the reverse. The craftsmanship appears to be of standard mass-market quality typical of vintage boutique or high-end department store costume jewelry of that era. The value estimate of $45–$85 is based on the assumption that these are well-preserved vintage pieces in good working order. Market demand for 1980s ‘statement’ jewelry remains steady among vintage collectors, though unsigned pieces generally command lower prices than those bearing hallmarks of recognized designers like Givenchy or Kenneth Jay Lane. Because there are no visible maker's marks, it is difficult to attribute these to a specific house; should they be identified in the future as a known designer brand through hallmark verification or archival catalog matching, the value could increase to $150 or more. Conversely, if physical inspection reveals significant metal pitting or if the enamel is actually plastic with significant surface wear, the value would likely fall below $20. To provide a more accurate valuation, a physical examination would be required to test the metal, verify the closure type, and check for any obscured signatures or stamps on the reverse side of the clips or posts. Documentation of provenance or an original box would also assist in refining this estimate. At present, they are appraised as attractive, unbranded vintage costume accessories in the Art Deco style.
