What is Bronzite?
Bronzite is a member of the pyroxene group of minerals, belonging with enstatite and hypersthene to the orthorhombic series of the group. Rather than a distinct species, it is really a ferriferous variety of enstatite, which owing to partial alteration has acquired a bronze-like sub-metallic luster on the cleavage surfaces.

- Lustre: Vitreous to submetallic (bronzy schiller).
- Hardness: Mohs 5–6 — about as hard as a steel knife.
