Vintage rhinestone ribbon brooch

This is a decorative costume jewelry brooch crafted in the shape of a ribbon or bow, featuring a complex configuration of colorless faceted glass rhinestones set in a silvery-tone metal base. The physical construction incorporates a mix of several different rhinestone cuts, including small round chaton stones forming pavé-style borders, large marquise or navette-cut stones accentuating the loops, elongated baguette-cut stones forming dangling ribbon tails, and a central circular stone acting as the knot. The metal backing appears silver-toned, though minor surface wear and patina are visible on the reverse or prong settings upon close inspection. There is no clearly visible maker's mark, signature, or hallmark in the provided photograph, so the attribution rests entirely on the visual design, materials, and construction techniques. The stylistic elements are strongly consistent with mid-20th-century costume jewelry, potentially dating from the 1940s to 1960s, a period frequently associated with prolific costume jewelry manufacturers such as Trifari, Coro, or Eisenberg, although no specific brand can be verified from this image alone. The piece shows overall good visual preservation with sparkling stones intact, though standard signs of age-related tarnish or light wear to the metal plating may be present.

Based on what I can see in the provided image, this vintage costume jewelry brooch is crafted in a ribbon or bow shape featuring a mix of chaton, marquise, baguette, and central round colorless rhinestones set in a silvery-tone metal base. I cannot verify from a photo whether the metal plating is rhodium-plated or sterling, nor can I examine the back closely for maker's marks or verify stone settings, which would need physical inspection to confirm. Although stylistic elements resemble mid-20th-century work from prominent makers such as Trifari, Coro, or Eisenberg, I must treat this attribution strictly as a working hypothesis since no visible signature or hallmark can be seen in the photograph. Market demand for mid-century rhinestone ribbon brooches remains steady among vintage costume jewelry collectors, with similar unsigned pieces typically selling in the $75 to $150 range. If physical inspection were to reveal a prestigious signature consistent with top-tier mid-century manufacturers, the value could potentially shift higher. Conversely, if the piece turns out to be a later reproduction, replica, or an unattributed item in the style of mid-century design, the value would likely drop to the $25 to $50 range. To establish a more precise evaluation and assess authenticity, an in-person examination by a qualified jewelry specialist, detailed hallmark verification, and professional appraisal are recommended.
