Vintage Sterling Brooch/Pendant Screwback Earrings

Great estate sale find! Believe they're from the 1940's. Earrings marked "Sterling" on round ends of screwbacks. They'd be even more stunning if the backs were converted with loops to make them dangle! Brooch isn't marked, but believe it's Sterling as well. Brooch is just under 3" wide. It also has a ring so it can be hung from a chain as a pendant.
