Set of 3 Joan Rivers Crystal Clip-On Earrings

Three prong-set crystal clip-on earrings from Joan Rivers. All earrings are set in silver toned metal, and signed. There is a clear earring with a green sparkle, a milky-white earring with an opalescent sparkle, and a pale blue earring. Clip style is hinged screw. Earrings are approximately a half-inch in diameter and are all in excellent pre-owned condition. Note: I don’t know what material these crystals are made of. There is a similar set that appears to have genuine Swarovski crystals, but I cannot confirm that these are exactly the same set as these did not come with the original packaging.
