Looks like either waterworn sandstone or jasper. The hardness should be able to make that distinction.

Is there a meter to buy for hardness?

Dear Weasel, it is really easy to test the hardness of a rock. All you need is a (empty) glass bottle or a piece of window glass:

But I'm thinking it is a jasper.

I had a good look again at the picture; rough jasper does not have little holes.

I found a nice website about sandstone: http://www.sandatlas.org/2012/08/sandstone/

What did the Mohs test tell you?
