Banded Jasper Crystal Skull

This material came from California. About 35 years ago I used to know a miner that had a yard full of rock he had collected over his lifetime. I used to visit him and listen to his stories as I browsed. I would make a pile of my own and then negotiate with him. This is one of those rocks. It almost looks like a banded Poly-Chrome Jasper. The colors are right. It's unusual anyway.

Size 3 7/8" front to back

Weight 1.63 LB
