Dyscrasite, a rare silver antimonide, doesn't often form clearly defined larger crystals, but discoveries at Uranium mine No. 21 at Príbram in the Central Bohemia Region, Czechia during the the 1980s provided some of the finest sculptural display specimens of this species. Specimens from this mine typically present unusual delicate flattened grey metallic bladed crystals of Dyscrasite rising up from massive dull grey Native Arsenic matrix. Sometimes these blades are twinned and a few can be seen on this lovely miniature-sized specimen. The untwinned crystals reach 1 cm in length. This fascinating crystal form is an icon of Czech mineralogy. Ex Hans Engelbrecht Collection, no. 4400, who acquired it in 1992.
