Peterson Mountain
Washoe, County, Nevada
A museum-quality gemstone, this is believed to be the largest and finest amethyst ever fashioned from rough retrieved in America—from the desirable Peterson Mountain locality in Nevada. The fine faceting of this oval-shaped stone brings added life to the astonishingly rich violet hue. The stone displays excellent transparency and a bright luster.
Weighing approximately 337.0 carats and measuring 58.0 x 37.5 x 27.5 mm
