That's a lot to take in.I'll go with granite. The specimen is characteristic of intrusive igneous rocks and one can identify on visual inspection the quartzite inclusions formed in concert with two distinct kinds of feldspar (plagioclase and potassium-rich potash feldspar). As for origin, I'd call your orbicular rock a "geofact." A geofact (a portmanteau of geology and artifact) is nothing more than a natural stone formation that is often most difficult to distinguish from a man-made artifact. Isn't earth science a hoot?

I believe it geo special cutter to cut it open and there's crystals in itOne rock.....
Don't have to be a dick and brag...
Only joking!
I'm no geologist, so I can't help..
I have to deal with so many rocks, it isn't funny!
There are some incredibly smart folks on here..
Hopefully one will chime in?
I definitely is not a geode. It is solid granite and will not be hollow.I believe it geo special cutter to cut it open and there's crystals in it
