Description
Interchangeable layers of concentric, botryoidal lead gray native Arsenic and Stibarsen (Allemontite) from well known Czech locality Třebsko 10 km southwest of Příbram. As little bonus there is a small spray of metallic Stibnite on one side of the piece. Classic material from a long-time defunct location and consequently such stuff becomes more and more rare.
