I found this stone in a homebuilt box today for $14. Underneath all the oil I felt there was a pretty decent stone. It reminded me a lot of one of the Eschers I have. So I took it home, broke it out of the box (I have not reverence and it was ugly). This is what I found. 1x1.75"x 8.25"light yellow brown. Its non-porous and has an interesting fault line through it.
Any ideas as to what type of stone it is?Attachment 123134
