Physical properties
Hardness: 5.5-6.5 on Mohs scale. Color: Steel-gray to black with a bright sparkling, glittery, micaceous appearance. Luster: Metallic to submetallic. Crystal structure: Trigonal. Streak: Characteristic reddish-brown.
Formation & geological history
Formed as a result of hydrothermal activity or high-grade regional metamorphism, where iron-rich fluids crystallize into plate-like micro-crystals of hematite.
Uses & applications
Primary ore of iron; used for ornamental carvings, polished cabochons, metaphysical crystals, and decorative display specimens.
Geological facts
Also known as specularite, its name comes from the Latin 'speculum' (mirror) because of its brilliant reflective micro-facets. Despite its metallic black look, rubbing it on unglazed porcelain leaves a rust-red streak.
Field identification & locations
Identified by its dense weight, high metallic glitter, and distinct reddish-brown streak test. Commonly found in major iron-mining regions like Brazil, South Africa, the USA (Lake Superior region), and Australia.
