Physical properties
Hardness 5.5-6.5 on Mohs scale, steel-gray to black color with submetallic luster, and a characteristic reddish-brown streak. It exhibits a rosette habit composed of thin, tabular crystal clusters.
Formation & geological history
Formed through precipitation from iron-rich hydrothermal solutions or aqueous sedimentary deposition. These rosette formations typically develop in evaporite environments or sandstone host rocks over millions of years.
Uses & applications
Primary ore of iron for steel production, widely used in pigments, and highly sought after by mineral collectors for its unique aesthetic rosette form.
Geological facts
Hematite rosettes are sometimes marketed commercially as 'iron roses'. The mineral has also been detected on the planet Mars by spacecraft instrumentation.
Field identification & locations
Easily identified by its distinctive rose-like cluster structure, high specific gravity, and reddish-brown streak. Prime specimens are notably found in the Novo Horizonte region of Bahia, Brazil.
