Vintage Swarovski Shell Earrings

Beautiful, petite shell shaped clip earrings, goldtone with clear crystals. 0.5 inches long. Marked Swarovski. Sadly, one crystal is missing but the metal behind it is bright silvertone so it just looks like a slightly grayed crystal. (See picture 4.) Not noticeable when on. Otherwise, these are in exceptional condition! The goldtone is perfect. Looks like they may have never been worn.
