Stibnite

Found in low-temperatures hydrothermal veins or replacement deposits and in hot spring deposits, this mineral is characterized by its bladed crystals and lead-gray color. The name reflects its antimony content. The Greek name for the mineral was "stibi" from whence came Latin stibium and the old name for the element antimony (Sb).
