Ivory color & Marcasite earrings

Large pear shape, ivory color dangle earrings with marcasite center and gunmetal frame. The marcasite has square cut crystal in center. Gunmetal hooks have tiny crystal stones. These are very different. They are ivory color, not white. Flash shows white. Worn one time. Very fashionable with dresses, suits and classic or dressy attire. These beauties are 2" from bottom of gunmetal hooks. I don't see them with casual wear. Picture of backs is truest color. In collection...
