A hefty chunk of brown rock is almost entirely coated with quartz, some of which has an unusual crystal habit. Many areas of the white quartz display a bright green coating of conichalcite, which shoes no crystal form even under a loupe, although some areas appear botryoidal. Much of the conichalcite has a layer of quartz crystals over it, giving it a bit of sparkle.
