Thanks MM but I do believe the second is natural. The inside is black in color and glassy in texture. The first one is wet so the colors will come out. I dont find much Jasper so it was a special find for me. Ill show a piece of the black one when the cortex is removed. This is a different rock I am showing. The first one is a finished NA artifact and the second one is one they started but never finished. I found all of these in a known camp site. Hope you enjoy, rock
