Vintage Etruscan-Style Costume Clip-On Earring

This is a prominent vintage costume clip-on earring, exhibiting a classic Etruscan revival style with an ornate, multi-stone cabochon configuration. The central feature is a large, butterscotch or cognac-colored amber-toned faux resin cabochon, surrounded by four smaller circular cabochons in deep garnet and black tones. The metalwork is a matte gold-tone finish with extensive decorative detailing, including rope-twist filigree borders, beaded accents, and volute-like scrollwork that creates a rich, textured surface. The earring measures approximately 1.5 inches in diameter. The metal structure appears to be a cast base metal with a heavy gold plating, typical of high-end costume jewelry makers from the mid-to-late 20th century, roughly late 1960s to early 1980s. The clip mechanism on the reverse is visible and appears functional, though it shows some slight tension wear. Condition-wise, the item shows minor surface oxidation on the metal accents and faint micro-scratches on the central resin dome consistent with light handling. There are no missing stones or significant structural repairs observed. The craftsmanship suggests a designer quality piece, reminiscent of work by Kenneth Jay Lane or similar high-fashion costume brands of the era.
