This is an adorable 3/4" beetle made of a light gold tone with green and clear rhinestones on the body with a red enameled stripe down the center of her back. She has a green enameled head and two red rhinestone eyes, six tiny feet and two antenna.  There is a C clasp and a rivited plate connecting the pin stem to the body indicates that this is an older piece.  Circa 1940, the stones are in remarkably clear condition.
