These pretty earrings have a Deco design at the ear and drop into a lovely pendant with a chaton amethyst stone and three rhinestones in a shiny gold tone flur-de-leis background.  Although not formally a set, these earrings match very well with #414 amethyst and rhinestone brooch from the 1940s. 1 3/4" total length including ear piece with a screw back.
