Hello again. Here I have a piece of something of which I can't identify. All I know is that it was collected by my Grandmother from somewhere in the U.S. The only thing I can tell is that it is obviously opaque and feels very dense. I this some sort of river rock with layered sedimentation? Thank you Henry

Very cool. A type of layered jasper?

Could also be banded iron formation (BIF) - not all is red and oranges. I'd cut off an end to see if you can get a view of an un-weathered surface.
