National Silver Rose & Leaf Spoon Earrings. At Midnight Jo all of our spoon earrings are handmade using actual vintage flatware. These earrings were made with silver plated flatware in the 1937 Rose & Leaf pattern by National Silver Co.. These earrings measure approx 2 1/2" long including the lever backs. These earrings come standard with silver plated lever back earwires, sterling silver lever backs are available at additional cost. How adorable!
