What is this rock?

Question

Found it next to a stream in Maryland

Answer 1

................................. Quartz??

Answer 2

It's a rock solid one

Answer 3

I'm not even convinced it is quartz but it does look like it. It looks like it could be a piece of some igneous rock or metamorphosed igneous rock.

Answer 4

It's a fire stone

Answer 5

Looks like Quartz
Smell it
Was there a Volcano ever there ?

Answer 6

I need better glasses to say. There is apparently quartz in it, but what all is in it, in total? too blurry. Cannot even tell if it is a vein or metamorphic.

Answer 7

Looks like quartz, possible rose quartz (which can appear purplish as in the photo).
Quartz can make a large part of a rock, mixed in with mica or other soft minerals.

Answer 8

That's a piece of wood. Oh, wait, you mean the little thing in the middle there? Can't say--it looks like it could be glassy industrial slag to me, or otherwise some kind of conglomerate. Were there any kind of industrial activity in the area in the past?
