AI Appraisal Estimate

This item is a tiered, starburst or snowflake-shaped costume jewelry brooch. It features a central round faceted stone surrounded by two concentric layers of navette-cut (marquise-shaped) rhinestones. All stones are finished with an aurora borealis (AB) coating, which creates an iridescent shimmer of pink, gold, and blue across the facets. The stones Appear to be prong-set into a gold-toned metal frame, a construction technique and aesthetic consistent with mid-20th-century costume jewelry, particularly from the 1950s or 1960s. The tiered design adds significant three-dimensional depth to the piece. No maker's mark or signature is visible in the provided image; similar styles were produced by many manufacturers of the era such as Weiss, Kramer, or Coro, though an attribution cannot be made without a physical inspection for stamps. The metal shows minor signs of age-appropriate patina and surface wear, while the rhinestones show high-quality light refraction consistent with leaded glass. The attribution to a mid-century period is a stylistic hypothesis based on the specific use of AB-coated navettes and the multi-level setting design.

Based on my examination of the image provided, I have evaluated this tiered aurora borealis (AB) rhinestone snowflake brooch. I can see a three-dimensional construction with prong-set navette and round stones, which is characteristic of mid-century costume jewelry. While the shimmer and facet clarity suggest leaded glass, I cannot verify the material composition or the security of the settings without a physical inspection. The design is consistent with a stylistic hypothesis of 1950s–1960s production. No maker's mark is visible; while the quality is reminiscent of manufacturers like Weiss or Kramer, I cannot identify a specific maker from this photo alone. My value estimate is based on the item being an unsigned piece of high-quality vintage costume jewelry in good condition. Typically, pieces of this type that bear a recognized hallmark tend to command higher prices, while an unattributed piece relies solely on its aesthetic and structural integrity. The market for mid-century AB jewelry remains steady among collectors who value the iridescent finish. To move beyond this working assumption, a physical examination is required to check for hidden stamps on the pinstem or frame and to assess the metal for any significant plating loss not visible here. If this were found to be a modern reproduction rather than a period piece, the value would likely decrease to $10.00 - $15.00. Conversely, if a signature from a premium maker were found, the value could exceed $100.00. Providing provenance or original packaging would also be necessary to solidify a higher market position.
