It's fairly smooth. I agree the vein is quartz.
I think it might be petrified wood
I don't know. Petrified wood isn't all that common. Why do you think it's that?
To me it looks like a finegrained, silicious, sedimentary rock. Might be slightly hydrothermally altered or metamorphosed, can't really tell from the photos.
That's not to take away from the coolness of the rock though. It absolutely is a cool rock. I absolutely adore that quartz vein.
