Vintage Florenza Black Stone Fleur de Lis Brooch

Vintage Florenza Fleur-de-Lis Brooch. Black marquise stones and round stones. The metal is a gray/white-ish enameled metal. that is achieved with a black wash over the white enameling which you can see better on the back. Florenza is stamped in black lettering over the white wash; some of the letters are worn. I do not know if this is a reproduction or truly Florenza but have priced it as a non-piece. Very good condition. 1960's.
