VTG Black Stone Fan Brooch MCM Art Deco

This vintage Mid-Century Modern (MCM) costume jewelry brooch highlights a striking, oval-faceted black stone (likely glass or lucite) nestled in a polished bezel. The centerpiece is framed by a rich, gold-toned base boasting stylized, fluted sunburst or fan-like accents that evoke a strong retro Art Deco influence. It is a classic example of bold cocktail accessories popular between the 1950s and 1970s. See pics.
