Aurora Borealis Blue Round Vintage Crystal Clip Earrings Prong Set Signed WEISS?

This listing is for a pair of vintage, blue aurora borealis, crystal clip earrings. All of the stones are prong set and are different shades of blue depending on the lighting. The clips are in perfect working order and completely tarnish free. They measure approximately 3/4" in diameter. I would date these mid 1960's. They are signed on the back. It looks like a partial Weiss signature or a sequence of numbers. I will include a generic dust bag for storage. Buy with confidence, careful packaging promised. I love to bundle. Drawer 21
