Formation & geological history
Formed in mafic and ultramafic igneous rocks like pyroxenites and gabbros through magmatic crystallization. It is a variety of Enstatite with high iron content.
Uses & applications
Primarily used as a decorative gemstone for jewelry (cabochons, beads) and as a stone for metaphysical collecting.
Geological facts
Bronzite is known for its unique 'schiller' effect, a submetallic luster caused by the reflection of light from minute parallel inclusions within the mineral.
