I bought these at a tag sale held by the lady who is named on the label on this card of earrings - Cara Lee. She said a friend of hers used to make these earrings in the 60's. They're made of clay or some sort of polymer and hand decorated in shades of blues and greens.
The pierced earrings are the old fish hook style, so I'm confident of the dating. They look unused.
At 2 1/2 inches in length, these groovy earrings are in excellent condition.
