I was at a local antique mall today and saw this stone, I paid $12 for it and it looks like S!*%, like a dang bear got ahold of it. But it is a natural stone I am almost certain by the veins you can see in the side photo and it is very fine where the chips are and you can see bare stone. Please someone tell me I scored a sweet finishing stone on the cheap. here's the pics. Let me know if I need to take more.
