Vintage Gold-Tone Circular Openwork Lion Brooch

This is a vintage circular brooch featuring a stylized, openwork (pierced) design of a lion's face and mane. The item measures approximately 2 to 2.5 inches in diameter and is crafted from a bright, polished gold-tone metal, likely gold-plated base metal or high-quality brass. The design is modernist in style, utilizing negative space to define the features of the lion, including the eyes, snout, and a radiating mane that fills the circular perimeter. The surface is highly reflective with a mirror-like finish, finished with smooth edges indicating quality casting and hand-polishing. A horizontal pin stem with a safety c-clasp is visible through the openwork sections on the reverse side. The condition appears excellent with minimal surface scratches and no significant tarnishing or loss of plating, suggesting careful storage. While no maker's mark is visible from the front, the aesthetic is consistent with mid-to-late 20th-century costume jewelry designers like Trifari or Monet, typically dating from the 1970s or 1980s. The craftsmanship shows high-tension metalwork with crisp, clean cutout lines and a substantial overall weight.
