Vintage 80's Earrings Metallic Tone Crackle Finish Silver Blue PInk Tone Pierced

Vintage 80's Earrings These unique fun earrings have a metallic look to them and have a crackle finish. They seem to be possibly artisan made. Colors include hot pink, blue tone, silver tone, purple and greenish blue. I am unsure of the material they are made of, but it doesn't appear to be a metal. Pierced Gently used. There are some small circular indentations on the front of them, but this may just be part of the earrings. There is a little wear to the back of them.
