Antique gold tone leaf & blue rhinestone necklace and screw back earrings

This gorgeous goldtone leaf and dark blue rhinestone necklace and screwback earrings set belonged to my grandmother. I believe from the 1920's. Signed on the back of earrings but can't read see photos. Some tarnish and wear but good condition considering the age. Still very wearable. Will add length of necklace for reference soon. From a smoke-free but cat friendly home. I use recycled shipping packages when possible for the environment. Please let me know if you have any questions
