Rhinestone-set floral brooch in the mid-20th-century style

This item is a costume jewelry brooch designed in the shape of a flower on a curved stem. The flower head features ten marquise-cut, light blue rhinestones arranged as petals around a central round iridescent aurora borealis (AB) rhinestone. Attached to the stem is a single marquise-cut blue rhinestone leaf and a small, square-cut yellow or amber-toned stone. The stem itself is set with a row of small, clear round rhinestones in a channel or pavé-style setting. The metal setting appears to be a gold-tone or brass-colored base metal with individual prong settings for the larger stones. In terms of condition, there is visible surface grime, some darkening of the clear stones consistent with foil degradation, and a slight tilt to the central stone. The design is stylistically consistent with mid-century costume jewelry (specifically 1950s–1960s), though there are no visible maker's marks or signatures in the image to facilitate a more specific attribution. The craftsmanship reflects typical mass-market costume jewelry of that era, utilizing prong-set glass stones. Any specific manufacturer attribution would require physical inspection for hidden marks on the reverse.

Based on the provided image, I have examined this costume jewelry brooch which appears to be designed in a mid-20th-century floral motif. The item features blue marquise-cut rhinestones and a central aurora borealis (AB) stone on a gold-tone setting. While the design is stylistically consistent with 1950s–1960s mass-market manufacturers such as Coro, Trifari, or Lisner, I cannot identify a specific maker's mark from the photo. Any attribution remains a hypothesis, as I cannot verify the reverse for hallmarks or signatures without a physical inspection. The value estimate of $25.00–$45.00 is based on the assumption that this is an unsigned piece from that era. The visible condition significantly impacts the valuation: I can see surface grime and darkening of the clear stones, which strongly suggests foil degradation or 'dead' stones. Furthermore, the central stone appears slightly tilted. These condition issues generally reduce collector demand compared to pristine examples. In the current market for vintage costume jewelry, unsigned floral brooches of this quality are common. If this item were later found to bear a desirable signature—such as 'Eisenberg' or 'Schiaparelli'—the value could increase to $150 or more. Conversely, if it is a modern 'in the style of' reproduction using lower-quality plastics rather than glass stones, the value would likely drop below $10. To confirm its origins and material composition, an in-person examination is required to check for hidden marks, test the metal, and assess whether the stones are glass or acrylic.
