AI Appraisal Estimate

This item is a circular, sunburst-pattern brooch featuring a layered filigree design. The base appears to be a silver-toned metal, possibly rhodium-plated or base metal, which showcases intricate openwork scroll patterns. The piece is set with several round-cut rhinestones featuring an 'Aurora Borealis' (AB) finish, which gives the stones an iridescent, rainbow-like shimmer over an orange or amber base. A central larger rhinestone is surrounded by a ring of twelve smaller stones at the ends of the filigree rays. This specific construction and the use of AB-coated stones are stylistically consistent with costume jewelry popular from the late 1940s through the 1960s. The stones appear to be prong-set within the metal framework. Visible condition issues include some darkening or patina on the metal surface and possible aging to the adhesive or foil backing of the rhinestones, typical of vintage costume jewelry. No maker's mark is visible in the provided image; therefore, any attribution to a specific designer like Sarah Coventry or Weiss would remain a hypothesis subject to physical inspection for a signature on the reverse pin assembly.

Based on my visual analysis of the provided image, this brooch appears to be a mid-century costume piece featuring Aurora Borealis (AB) coated rhinestones in a sunburst filigree setting. I can observe iridescent shimmer characteristic of the AB finish introduced in the mid-1950s, but I cannot verify the specific metal composition or the integrity of the foil backing from a photograph alone. The darkening seen on the filigree may be a standard patina or sign of metal wear, which affects secondary market desirability. The estimate of $25 - $65 assumes the piece is a quality unsigned vintage item or a mid-market brand like Sarah Coventry. If the piece were physically inspected and found to bear a mark consistent with a high-tier designer such as Weiss or Eisenberg, the value could increase toward the $85-$120 range. Conversely, if it is determined to be a modern reproduction or 'in the style of' vintage mid-century jewelry using contemporary plastics, the value would likely fall below $15. To confirm the value, a physical examination is required to check for a maker's mark on the pin assembly, test the metal, and assess the stones for chips or 'dead' spots not visible in this lighting. The market for mid-century costume jewelry remains steady, though buyers typically favor pieces with verifiable signatures and minimal foil degradation.
