Vintage CATHERINE POPESCO Style Brooch Pin Rhinestone Enamel Mid Century Jewelry France. Circa 1960's. This stunning pin has glistening rhinestone flowers and green enameled leaves. I don't see a Catherine Popesco marking on it but, it looks exactly like her signature pieces. I'm not sure if everyone of her jewelry pieces are marked or not. Depending on the light source the pin displays different vibrant greens. The dimensions are 2.50" tall by 2" wide.
