Vintage Modernist Gold Tone Brushed Annular Brooch Pin

A beautiful and classic vintage annular (circle) brooch, likely dating to the 1970s. While this piece is unsigned, it exhibits the high-quality design and manufacturing "tells" characteristic of the era's leading American jewelry makers. The finish is a sophisticated combination of soft, brushed satin gold-tone with bright, diamond-cut engraved accents. The construction from a durable, non-magnetic base metal and the quality of the plating are hallmarks of top brands like Napier, known for their sculptural metalwork, or Monet, celebrated for their high-quality plating. This is a timeless and versatile piece of vintage costume jewelry.
