Need help identifying stone. Many, many hand tool marks. Have additional photos of bottom of stone.

Looks like a rock to me. Keep looking! Welcome to TNet!

I agree with Jonathon. I don't see any evidence of it ever being altered by man. Keep looking though.

I don't see any evidence of hand tool marks so it's just a rock. Kinda looks like Chinese writing on there though, so maybe it's related to the Kensington stone.
