Pyrite Mineral Uses and Properties
Identifying Pyrite. Hand specimens of pyrite are usually easy to identify. The mineral always has a brass yellow color, a metallic luster and a high specific gravity. It is harder than other yellow metallic minerals, and its streak is black, usually with a tinge of green. It often occurs in well formed crystals in the shape of cubes, octahedrons, or pyritohedrons, which often have striated faces.
