1920 Czechoslovakian Purple Glass Dangle Earrings

c1920 Late edwardian earrings from Czechoslovakia. The material appears to be a low grade silver-it is not magnetic and shined up nicely when I polished with a cloth. The earrings have faceted glass that mimics amethyst. The center oval glass measures 16x20mm and is beze set in a saw tooth floral mounting. Lovely details-filigree style cap to the center dangle. From top to bottom 2 3/4" x 7/8" wide. Screw backs.
