Physical properties

Formation & geological history

Formed as secondary minerals through the weathering and oxidation of iron-rich rocks (gossans) or hydrothermal deposition in cavities and fractures. Found in sedimentary and volcanic environments.

Uses & applications

Used primarily as iron ore for steel production, pigments for paints and cosmetics, and as unique collector specimens or grounding stones in metaphysical practices.

Geological facts

Hematite is derived from the Greek word for blood (haima) because of its red streak. Botryoidal refers to its grape-like cluster habit. This specimen displays a crust of iron oxides over a quartz or stone base.

Field identification & locations

Identified by its distinctive bubbly (botryoidal) shape and 'rust' red-to-brown color. Look for it in iron mines, volcanic cavities, or weathered outcroppings. The reddish-brown streak is a definitive identifier.
