“14 x 12.5 x 9 cm. Strikingly similar in appearance to the famous Japan Law twins, so-called "Gitter Quartz" is found in the western Erongo Mountains and the nearby Klein Spitzkoppe in Namibia. They can form a dense three-dimensional lattice of crystals, hence the German name "Gitterquarz" ("fence" or "lattice" quartz). This spectacular specimen features a stunning pair of Smoky Quartz crystals 13 cm across. Coming out from their bases, almost at 90 degrees, is another 5 cm crystal that is quite gemmy, in fact. All are on a huge Orthoclase crystal that is 5 cm across. Quartz can be notoriously hard to mine, and some of the lesser crystals are clearly missing or damaged, but six of the main crystals, including the three largest, are all in great shape. One of the best examples of this rare form of Quartz the I have seen. Aesthetic and most unusual. Ex. Charlie Key. ”
