Old-time, quality Proustites from the historic Pribram locality are rare, and this cluster is a fine representation for both locality and species. The intergrown crystals have a very good metallic luster, and the largest of the crystals is 1.3 cm across. The crystals do show the classic "ruby-silver", cherry-red color when backlit, but only along the very edges because the crystals are so stout. A good, highly representative thumbnail of an important species from an equally important location.
