Handmade Vintage Earrings

Handmade, signed by the artist ,vintage rhinestone earrings. Purchased these in the late 1980s at a boutique. I am unable to make out the artist name. Looks like they’re made out of clay and rhinestone, clip on earrings. Please look at pictures. One of the earrings has a small mark on the side which is barely noticeable, otherwise in excellent condition, considering the age.
