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.

I have examined the Vintage Gold-Tone Circular Openwork Lion Brooch via high-resolution digital imagery. This piece reflects a 1970s-mid-1980s modernist aesthetic, characterized by its bold circular openwork and stylized leonine features. The condition appears to be excellent; the high-polish gold-tone finish remains bright with no evidence of base-metal pitting or 'verdigris' oxidation, suggesting superior plating quality typical of brands like Monet or Trifari during their peak production years. The market for unsigned vintage costume jewelry remains steady, though values are significantly higher when a designer attribution can be verified by a hallmark. Comparable unsigned modernist animal motifs in this size range frequently sell within the $35 to $60 range, while attributed pieces soar past $100. This piece's rarity is moderate; while lion motifs are a staple of the era, the 'negative space' design is particularly striking and appeals to contemporary fashion trends. The primary value-driving factor is the pristine surface condition—any significant scratches would devalue this by 50%. It is important to note that this appraisal is based on visual examination alone. A physical inspection is necessary to verify the base metal weight, the security of the safety c-clasp, and to search for hidden maker marks often tucked into the interior rim. Definitive authentication of the gold-plating thickness would require a non-destructive XRF (X-ray fluorescence) test, though this is rarely performed on costume pieces. Provenance documentation, such as the original jeweler's box, would further solidify its market standing.
