Vintage Cameo Gold Pearl Clip on earrings

Vintage gold tone earrings with pearl accents. Unsure of gold and pearl quality. 4 of the 8 pearl accents are missing from 1 of the earrings. Screw back, clip ons. These are very old but still retain their color well. They were my great grandmother's, so I am guessing 1920's. Black background on white cameo lady. Statement or decorative piece for a vintage theme or just a beautiful addition to your vintage collection.
