Stone Chisel and preform?

[Appalachian Woodsman]

I was detecting a 1750s farmstead and picked up a solid signal. Upon unearthing it, I found this rock. I've not seen this type of rock, and first thought was an unfinished preform tossed in process. I'm prepared to hear it's just a rock though. (The target signal ended up being a colonial flat button).




I picked up another good signal that produced nothing great but above it as well was another stone find. This one appeared to be a stone chisel with one end broken.

Am I accurate on my assumption of this being a chisel point? Or is it just a very symmetrical, natural creation?



Thank you for any insight provided.

That's what they look like.

I have a couple of chisels much like yours. Mine looks like a different type of stone. Found in the foot hills of Appalachia.

Here's some pics of one of them. The coin is a silver dollar, not a quarter.
