1960's vintage costume clip on earrings

Straight out of the 60's For your consideration today is a small pair of aurora borealis crystal clip on earrings. They measure approximately 1" wide and each weighs in at 5 grams. There are no missing or replaced stones. The earring is reticulated to allow in maximum light. The clips are tight and there is no tarnish. There are no hallmarks. Thanks for taking the time to look and to read!
