Pyrolusite is a mineral that can form into crystals, and is an important ore of manganese: Pyrolusite is black or bluish-black in color, with a metallic luster and a black or bluish-black streak. It can have a soft texture and soil your fingers. When well crystallized, it can be harder than glass. @Northern Lights Crystal Co
