Pyrosmalite is a mineral in the pyroxene group with a distinct iron and manganese silicate composition. It often forms elongated prismatic crystals with a vitreous to submetallic lustre and a green to yellow-green color that can be translucent to transparent in well-formed specimens. The mineral commonly occurs in high-temperature hydrothermal veins and skarns, and notable localities include classic occurrences in Australia and Sweden where well-formed aggregates and sizable single crystals have been recovered.

About Pyrosmalite
Collectors value Pyrosmalite for its clean, crisp crystal faces and bright coloration, as well as its association with other rare sulfides and silicates in complex ore deposits. Exceptional specimens show sharp terminations and pleasing refractive qualities, making them appealing for display and study. Its occurrence alongside minerals of similar chemistry enhances collecting, providing a window into the hydrothermal processes that crystallize silicates with iron and manganese.
