A marvelous natural uncleaned quartz crystal cluster from Arkansas that has a large window activation, and a square back bottom because it formed on top of a calcite bed which later weathered out leaving square cavities on the bottom. This beauty has a brown/orange iron oxide coating and a partial coating of black botryoidal goethite. There is a small ding at the tip of the largest point. Stands on its own. Weighs 7.5 oz. Size: 3 3/4" long x 3 3/4" wide x 2 1/4" tall.
