Description
Berzelianite is an uncommon copper-selenide and here we have an unusual rich ore specimen from the well known Czech locality Bukov Mine near Rožná of Žďár nad Sázavou Distric. This great piece consists mostly of steel gray, nicely iridescent and metallic lustrous masses of Berzelianite tightly intergrown with the matrix. The Bukov mine is an abandoned uranium mine, now part of Rožná I and Rožná III underground system.
