72 Pound Quartz Geode Agatized Petrified Opalized Stone For Sale

72 lbs. Quartz geode formation I actually think there may be several open crystal areas within this rock you can see a tiny one aside from the bigger one and if you follow the quartz shade around from the bigger one you can see where its darker inside suggesting an opening. Or at the very least some very clear quartz. I took 3 pics with a flashlight on the other side of it so you could see the light coming through. It did give me all sorts of display ideas. Its encapsulated by stone petrified jasper agate, maybe opal.  There is a crazy amount of awesome to this very heavy stone.
