Blue Rhinestone Half Hoop Earrings 1940s Screw Back Silver Gold Tone Aqua

Two lovely pair of earrings. Both are half hoop style - one silver tone and the other gold tone. Both have aqua and clear rhinestone accents. The gold pair have screw backs and are marked. I can't quite read it. The silver pair are clip on style and not hallmarked. Both have plating loss/wear but are still sparkly and eye-catching
