Vintage Gold-Tone Layered Flower Brooch and Clip-On Earring Demi-Parure

This is a vintage three-piece demi-parure costume jewelry set, consisting of one large brooch and a matching pair of clip-on earrings. Each piece features a multi-layered, three-dimensional floral motif resembling a dahlia or chrysanthemum. The metal is a gold-tone base, likely brass with a matte or brushed satin finish on the petal surfaces, contrasted by polished edges that create a subtle sense of depth and movement. Each flower is centered with a large, round-cut clear rhinestone or faceted glass crystal, secured in a multi-prong setting within a textured floret cup. The brooch is significantly larger than the earrings and includes a decorative stem and leaf detail protruding from the bottom. The construction demonstrates mid-century assembly techniques, likely dating from the 1950s or 1960s. The condition appears fair to good for its age; while the metal retains much of its original luster, there are visible signs of tarnish and darkening at the petal tips and recessed areas, suggesting minor oxidation of the plating. The crystals show consistent brilliance, though closer inspection for foil-back degradation would be necessary to confirm long-term stability. This set represents a classic examples of high-quality mid-century seasonal costume jewelry by makers like Coro or Trifari, though no specific maker mark is visible in the provided image.
