North American Rift (RIFT6)
Notes specific to this specimen: A very dynamic piece. Beautiful snow-white quartz veins with a unique deep Smoky Quartz crystal vug in one of the complex fractures of jet-black Rove Formation. Never seen anything like it. Usually when the veins have crystals they are simply terminations of the predominant mineral filling the fracture. But not in this case! This piece is 100% natural with no cuts or polishings.
