Vintage green leaf screw-back earrings

Vintage leaf earrings with green enamel on gold-tone metal. Good vintage condition: the metal has some discoloration, especially on the back, but the enamel is in great shape. No markings. Screw-back style, suitable for non-pierced or pierced ears. Screw mechanisms work well. The leaves have a natural shape and brush-stroke effect. They're about an inch tall (see photo #4). Please let me know if you have any questions! Comes from a smoke-free, pet-free environment. I may reuse shipping materials.
