Pre-owned Vintage Lisner Blue Molded Thermoset Flower Brooch with AB Rhinestones

This brooch is a quintessential example of mid-century American costume jewelry, produced by the Liner company during the 1950s and 1960s. Lisner was renowned for its innovative use of thermoset plastic, a durable, molded material that simulated carved stone or glass, often paired with sparkling Aurora Borealis (AB) rhinestones. Collectors prize these pieces for their high-quality construction, distinctively modernist floral designs, and vibrant color palettes. The market value for such pieces remains steady among vintage jewelry enthusiasts, especially when the molded elements are intact and the plating shows minimal wear. This piece is particularly appealing due to the sophisticated balance between the matte blue thermoset finish and the prismatic, light-reflecting crystals, reflecting the era's fascination with glamorous, feminine aesthetics.
