"On November 4, 1972 Lewis Sigmon uncovered this Amethyst crystal in the Reel Mine of Iron Station, North Carolina. The deep purple shade of the Amethyst was inconsistent with the color of other stones discovered in the same Lincoln County location, leading him to believe that the presence of manganese dust, thick on the mine floor, had given the crystal its remarkable color. The crystal is 2 feet wide, 2 feet deep, and 1 foot tall. (60 x 60 x30 cm). At 165 pounds (11.7 stone), the crystal is the largest Amethyst ever mined in North America. James McKinney of Spruce Pine made the crystal available for the exhibition."
