Swarovski earrings

The crystals are blue and black with silver. They are stamped with the swan on the inside of the hoop. I took a photo, but it doesn't show up very well. The original box and certificate will come with it. I think I wore these maybe once. Bought them at Borsheims in Omaha, Nebraska, a Berkshire Hathaway company of Fine Jewelry and Gifts (Warren Buffets store)
