The listing, Vintage Screw-On Aurora Borealis Earrings, Numbered has ended.
These earrings have 7 digits on the gold part of each earring. They also look like they have a name, but it is so worn, I just can't make it out for anything! Other than that, I don't see any markings, but the gold is is mint condition considering the age of these. I believe they are glass (definitely not plastic), and excellent condition (other than the name that's too worn). Awesome faceted reflections! I have other jewelry on auction now including gold and sterling, so check them out! U. S. shipping only.
