Large vintage amethyst purple paste 1930s Czech Art Deco rhinestone floral brooch with gold tone filigree

Lovely example of a 1930s Czech glass rhinestone brooch with amethyst purple rhinestones claw / prong set in antique gold tone. There is a lovely layered 3D element to the floral design. The brooch fastens with a secure roll-over clasp and pin - the back shows lovely construction and is almost as pretty as the front! It is in very good vintage condition.
