Sweet bows and wee lanterns - two pairs of vintage Coro earrings

The screw-on goldtone bows, an inch wide, are decorated with rhinestones and a silvery pearl at each centre. I would date them from the 50s. The little balls of hollow gold tone metal are ridged and pierced with evenly spaced pinholes. They drop about a half inch from their clips. Both pairs are in great shape and are signed Coro.
