Though showing some obvious breakage on one crystal, this specimen consists of several Smoky Quartzes that have reasonably good hexagonal prismatic form. One of these has no termination due to a separation from an adjacent crystal, but this is not human-induced, as the breakage point is healed over. The crystals average about 1.5" (3.8 cm) in length and have reasonably clean faces and edges that show a vitreous luster where they are not coated with a thin layer of limonite, white calcite, or pale green malachite. Their color is a combination of pale brown and violet, so that they could conceivably be construed as amethyst, and they are transparent and show moderate clarity, though some are heavily included and all are internally fractured to a degree. It is difficult to determine their clarity accurately, however, due to the interference of the various coatings that are on different sides of the crystals. I haven't seen many specimens like this one.
