Vintage Kokopelli Earrings 1980’s Pierced

These fun Kokopelli post earrings are vintage 80's. One owner. The earrings are not stamped, so I am not sure of their material. They were tested with a strong magnet, and were not attracted to it, so it could be silver or another non-ferrous metal. They are very light weight and approximately 3/4" wide. Questions welcome. From a smoke free home. Kokopelli embodies the true American Southwest and is known as a fertility god, prankster, healer and storyteller.
