Physical properties
Hardness: 5.5-6 (Mohs); Color: Bronze-brown with golden metallic chatoyancy; Luster: Submetallic, silky; Crystal System: Orthorhombic; Specific Gravity: 3.2-3.5
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.
Field identification & locations
Identify by its characteristic bronze-metallic sheen and dark brown base. It is frequently found in Norway, South Africa, and the USA (Montana/California). Collectors look for high chatoyancy.
