Vintage Japanese-Style Fan Motif Clip-On Earrings

This is a pair of vintage clip-on dangle earrings featuring an ornate fan motif with a Chinoiserie or Japonisme aesthetic. Each earring is constructed from an antiqued brass-toned base metal with a darkened patina finish highlights the recessed details. The earrings consist of a clip-on mechanism at the top that leads down to a decorative bow-shaped junction, from which an oval pendant hangs. The focal point of the pendant is a bas-relief design depicting a traditional folding fan overlaid with floral patterns, dragonflies, and foliage. The earrings measure approximately 1.5 to 2 inches in total length. The construction suggests mass-produced costume jewelry likely from the mid-to-late 20th century, specifically the 1970s or 1980s when Victorian-revival and Asian-inspired motifs were popular. Condition-wise, the metal shows a consistent aged patina with some darkening in the crevices, which appears intentional for a 'vintage' look. There is no visible sign of significant metal fatigue, though the clip mechanisms would need to be tested for tension. No designer marks are visible on the front or the visible portions of the clips, suggesting they may be unsigned boutique items. The overall craftsmanship is mid-grade costume jewelry, utilizing casting and stamping techniques to achieve the textured detail.

I have examined the digital images of these vintage fan-motif clip-on earrings. Based on this visual inspection, I have identified the items as mid-to-late 20th-century costume jewelry, most likely dating to a period of Asian-revival popularity during the 1970s or 1980s. The antiqued brass plating over a base metal alloy is consistent with mass-produced boutique jewelry of that era. The aesthetic condition appears fair to good; the patina is uniform, though typical oxidation and wear on the clip mechanisms are consistent with age. There is no evidence of high-carat gold or precious gemstones, which places these squarely in the collectible costume category rather than fine jewelry. The market for unsigned Chinoiserie jewelry of this type is stable but abundant, with similar pairs frequently found on secondary markets like Etsy or eBay. Rarity is low, as these were produced using standard casting and stamping manufacturing processes. While the level of detail in the dragonflies and floral motifs adds charm, the lack of a designer hallmark (such as 1928 Jewelry Co. or Coro) limits the ceiling for collectors. Limitations: Authenticity and valuation are based solely on visual data from photographs. I cannot verify the metallic composition, structural integrity of the spring-tension clips, or potential lead/nickel content without physical handling. A professional in-person acid test for gold content and a closer inspection for microscopic maker's marks hidden under the clip pads would be required for a definitive valuation. No provenance documentation was provided, which also impacts the historical value.
