This is a pre-owned pair of Kate Spade earrings. I do not believe I ever wore these earrings except to try on. They are in very good condition. The back and prongs are silver toned metal. However Im not sure what type of metal is used. The crystal is clear. One of the photos which is greatly magnified you can see the outline of a spade. The measurements are in the photos along with a size comparison to a dime. I also provide the weight of one earring in the photos. I attached new generic earring backs to the earrings. Included is a small Kate Spade dust bag. The earrings are stored in my nonsmoking home.
