This one is mostly matrix, and a small vug that makes it worth the five bucks I paid the same vendor as the other Quartz piece for. :3

As you can see, there are a bunch of baby crystals surrounding one large, perfectly faceted Smoky Quartx piece in the center. There aren't any dings on anything on the edges, as far as I could see using a loupe. Since looking at a big yard rock would be boring, I zoomed in on the point of interest and the photo turned out nicer than I expected!
