These clip on earrings are vintage and preowned with minor wear and patina from age. They are signed and tested. The gemstone are genuine stones. Size is approximately 2" 3/4 inch in length. I choose to leave the patina on the jewelry I sell and leave to the buyer to decide if they want to polish or leave patina. That being said these would polish beautifully if desired. See all photos feel free to ask any questions. Thank you.
