Physical properties
Hardness: 5.5-6.5 (Hematite) / 7 (Quartz); Color: Silver-grey, white, orange/rust; Luster: Metallic to earthy; Structure: Trigonal; Gravity: 5.26
Formation & geological history
Formed in hydrothermal veins or as a secondary alteration product in sedimentary and metamorphic environments, typically where iron-rich fluids interact with oxygen.
Uses & applications
Primary ore of iron (Hematite), ornamental specimens, or geological study.
Geological facts
Specular hematite gets its name from its 'mirror-like' tiny metallic flakes. The orange coloring is likely limonite or 'rust' from the oxidation of iron minerals.
Field identification & locations
Identify by its silver-grey metallic glitter (specularity) and the characteristic reddish-brown streak it leaves on a ceramic plate. Often found near iron mines.
