Here we have a fine old Russian "Fadenquartz" from the Robert Jakob collection.The crystals are excellent developed, razor sharp and gemmy. The terminations are superb and the overall aesthetics great. Faden Quartzes from Pakistan are now fairly well distributed due to a find a few years back, but Russian ones are very hard to get your hands on. Not to be confused with gwindels, though somewhat similar in form, these strange compound crystals are distinguished by the fuzzy "faden line" that runs through the center of the crystals, with the crystals growing out from this point in either direction to terminate in a row along either side. This one is undamaged and complete all around.
