From the 1930's this pot metal brooch is reminiscent of Art Nouveau jewelry in its theme of graceful exotic flowers and curves.  The stone is a clear, faceted amethyst colored and open-backed glass stone which is bezel set.  Four small amethyst glass chatons are hand set in prong settings.  The pot metal is molded with pierced openings that imitate filigree work.  There is a twisted rope border around the edges that are interrupted by the foliage.  Although this is a more crude execution of fine filigree work, pot metal brooches with this detail are becoming rare and do have a complex beauty not seen in later metal work.  In excellent condition, it measures 2" wide and 1 1/8" tall
