I posted this in the "What is it", and it was suggested to me to put it in the Indian Artifact section.
We found this piece recently in NE Wyoming, on a ranch that is known to have a couple of TeePee rings, but I don't know if it even is an indian artifact - or even what it is.
It is not metal. It is not magnetic, it will not sound off on the md at all, in any setting. It is heavy for its size, and looks and feels like stone.
One picture is the side view, the other two are the top and the bottom. That is my hand holding it, for size reference.
Thanks,
B
