Bronzite has an orthorombic crystal system, and is in the mineral class of oxides (hydroxides). It is a variety of Enstatite, which in its partial alteration has acquired a bronze-like sub-metallic luster on its surfaces. The black streaks found in it are due to its heavy iron content (Hematite). Sometimes it has also been called Axinite, a much more translucent stone.
Bronzite in its crystal form is rare. It is usually found as a part of igneous rocks, either as irregular masses or as very small crystals in volcanic rocks.
Bronzite is also known to be a common part of meteorites, usually found combined with Olivine formed in small spherical masses. Its coloring is generally brown (from earth) and in deep shades of green when it has come from meteorites. It is found in many parts of the world including India, Finland, Norway, and New York.
