9.5 x 4.6 x 4.0 cm. A simply STUNNING, GEM CLEAR quartz crystal so fine and sharp, that it looks carved. This was mined pre-WWII (judging by the Ward's label) and would have been then and now of a quality among the top percentile. Few quartzes are SO clean and clear, so crisp, and so pristine as this from Arkansas. The clarity must be seen in person to be believed. Ex. Richard Hauck Collection.
