Don't ask what it is. I almost never know. I buy large boxes of mixed rocks and almost never know what the pieces are. I don't really care. I just enjoy seeing all the different materials and what they look like as I cut them.

Most of the time the pieces that are sent to me are usually what the seller just wants to dump due to lack of interesting patterns. I cut, and cut, and cut, and grind, and when I get bored with a piece, I toss it into a bag of rocks for the tumbler.
The tumblers have a unique way of changing the not so great pieces into at least more interesting. It's a process of time and patience.
