This is a pair of pierced earrings that have silver tone hoops with a single aurora borealis crystal dangling in the center. The crystal is a very pale blue-green and appears to be made of molded plastic. The earrings are not signed and I do not know who made them. They measure 1-3/4 inches long from the top of the wire. The earrings are in good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
