Gold-tone and green stone clip-on earrings (unauthenticated)

The provided image displays a pair of clip-on earrings alongside a matching single earring component, resting casually in the palm of an adult's hand to provide a general sense of scale. Each piece features a polished, oval-shaped cabochon stone in a deep, mottled forest green coloration, suggestive of nephrite jade or a similar hardstone, though exact mineral composition remains completely unverified by physical testing. The stones are securely bezel-set within yellow gold-tone metal mountings that display a decorative, textured milgrain or beaded edge along the outer rim. The overall construction displays typical mid-century costume jewelry techniques, featuring standard hinged clip-on mechanisms on the reverses, which are partially visible on the upper paired pieces. There are no clearly legible maker's marks, hallmarks, or designer stamps visible in this photographic angle. The metal exhibits minor surface wear and a slight warm patina consistent with age, but no major structural damage, missing teeth in the bezel settings, or severe plating loss is immediately apparent upon visual inspection. The items display an aesthetic frequently associated with mid-20th-century fashion jewelry production, though precise age and metal purity cannot be established from the image alone. The identification rests strictly on visible physical characteristics and form factor.

Based on what I can see in the provided image, this lot consists of a pair of clip-on earrings and an extra matching component featuring polished green cabochon stones in gold-tone textured mountings. The aesthetic strongly suggests mid-century costume jewelry, displaying typical period design elements such as bezel-set hardstones and milgrain detailing. However, I can't verify from a photo whether the green stones are genuine nephrite jade, glass, or resin, nor can I test the metal composition or plating thickness. There are no clearly visible maker's marks or hallmarks in this photographic angle, leaving the exact manufacturer and period unverified. My value estimate of $45 to $85 assumes the attribution to mid-century fashion jewelry is correct, representing typical secondary market behavior for unsigned vintage costume pieces of this type and condition. If the items are physical reproductions, modern replicas, or generic 'in the style of' pieces rather than period-appropriate costume jewelry, the value would likely drop to the $15 to $30 range. To establish a higher value or confirm authenticity, I would need physical inspection to examine the construction techniques, hallmarks, and material composition closely, alongside potential scientific testing of the stones and metal.
