Vintage Floral Bouquet Rhinestone Brooch

This is an oversized costume jewelry brooch featuring a lush, asymmetrical floral and foliage motif. The piece is constructed with a silver-tone base metal and is densely pavé-set and prong-set with a variety of multi-colored faceted rhinestones. The palette is dominated by vibrant jewel tones including emerald green, deep turquoise, and sky blue. The design incorporates several stone shapes: a large oval emerald green stone at the top, numerous marquise-cut stones forming leaves and petals, round chaton-cut stones in varying sizes, and a circular element densely packed with tiny blue pavé stones. Some of the smaller peripheral stones appear to have an Aurora Borealis (AB) finish, giving them an iridescent shimmer. The construction indicates a mid-20th-century aesthetic, likely from the 1950s or 1960s, a period popular for bold 'statement' brooches. While no maker's marks are visible in this orientation, the complexity of the stone setting and the interplay of color suggest a high-quality costume piece. The condition appears fair to good; the stones remain bright with no obvious 'dead' or darkened rhinestones visible, though a close inspection of the metal backing would be required to rule out oxidation or pin-mechanism fatigue.

Based on my visual examination of this oversized floral bouquet brooch, I have identified it as a high-quality example of mid-century costume jewelry, likely dating to the late 1950s. The piece exhibits characteristic traits of premium manufacturers such as Schiaparelli or Eisenberg, though the absence of a visible hallmark suggests it may be an unsigned beauty or a boutique designer piece. The dense pavé and prong-set construction utilizing varied cuts—specifically the marquise and oval stones—indicates superior craftsmanship compared to mass-market molded pieces of the era. The stones appear vibrant with no evidence of 'graying' or foil-back deterioration. While the market for vintage costume jewelry remains stable, price realization is heavily dependent on the integrity of the AB finish and the security of the pin mechanism. Comparables for unsigned high-end floral brooches of this scale and complexity typically fall within the $200 range, with premiums paid for the specific 'jewelry-toned' palette seen here. However, I must note that an image-based appraisal has inherent limitations. To confirm full authenticity and provide a definitive value, an in-person inspection is required to check for 'dead' stones under 10x magnification, verify the weight/density of the base metal, and inspect the solder points on the reverse. Additionally, any provenance documentation regarding the original point of sale would significantly enhance the item's marketability and value ceiling.
