Vintage screw-back rhinestone earrings

This pair of vintage clip-on or screw-back earrings features a charming floral or starburst cluster design rendered in a gold-tone base metal. Each earring measures approximately three-quarters of an inch in diameter and showcases an openwork, filigree-like frame with curved, looping petal shapes radiating outward. At the center of each piece sits a cluster of four faceted, brilliant-cut sapphire-blue chaton rhinestones, securely prong-set to catch the light. The reverse side of the right earring reveals a threaded screw-back mechanism, which is characteristic of mid-20th-century non-pierced jewelry design. The gold-tone metal exhibits a warm patina with minor surface wear consistent with age and gentle use, though the plating remains largely intact. No maker's marks, signatures, or stamps are immediately visible in the photographs provided, so the identification rests strictly on the physical construction, material composition, and decorative style. The overall design and hardware are consistent with costume jewelry produced during the mid-20th century, frequently associated with the retro or mid-century fashion eras. The craftsmanship demonstrates standard commercial stamping techniques typical of mass-produced costume pieces from that period.

Based on what I can see in the provided photographs, this pair of vintage screw-back earrings features a charming mid-century floral cluster design with gold-tone filigree metalwork and sapphire-blue chaton rhinestones. The presence of threaded screw-back hardware suggests a mid-20th-century origin, consistent with common costume jewelry production of that era. However, I cannot verify from a photo alone the precise metal composition, plating thickness, or exact age, and I would need physical inspection to confirm these details. The earrings bear no visible maker's marks or signatures in the images, meaning any attribution to a specific designer remains a working hypothesis rather than a confirmed identification. The estimated value range of $45 to $75 reflects typical retail market behavior for unbranded mid-century costume jewelry in similar condition, exhibiting a warm patina and minor surface wear. Demand for vintage unsigned costume jewelry remains steady among collectors of retro accessories, though values are generally modest. If physical examination were to reveal that these pieces are later reproductions, modern replicas, or unsigned copies in the style of mid-century designs, the market value would likely decrease to the $15-30 range. To more fully understand the piece, an in-person examination by a qualified jewelry appraiser or costume jewelry specialist would be required to assess the hardware, construction techniques, and materials more closely.
