Vintage Gold-Tone Filigree Enamel and Rhinestone Costume Brooch

This circular costume jewelry brooch features a layered, openwork filigree design with a scalloped gold-tone metal border. At its center resides a large, round-cut clear rhinestone, prong-set and surrounded by an intricate cluster of smaller faceted crystal accents. The mid-section utilizes interlocking gold-tone loops accented by four larger rhinestones at the cardinal points and deep black enamel-filled sections that provide a dramatic contrast against the metal. Measuring approximately 1.5 to 2 inches in diameter, the piece exhibits characteristics typical of mid-20th-century American costume jewelry, likely dating from the 1950s or 1960s. The craftsmanship shows a high level of detail in the metal casting and stone setting, though it is constructed from base metal rather than precious materials. Visible condition includes some minor tarnishing of the gold-tone finish and slight clouding of the central stone, which are common signs of age. The absence of a visible maker's mark suggests it may be a boutique or mass-produced piece from a prominent era of decorative accessory manufacturing.
