Physical properties

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.
