Hematite

Hardness of 5.5-6.5 on Mohs scale, metallic to dull blackish-gray color, submetallic to metallic luster, and a reddish-brown streak.

Forms in diverse geological environments, particularly hydrothermal veins, sedimentary iron formations, and volcanic deposits.

Used extensively as an iron ore, in pigments, and polished as gemstones or worry stones.

Hematite is the primary ore of iron and gets its name from the Greek word for blood due to its reddish streak.

Easily identified by its characteristic reddish-brown streak and heavy metallic feel; commonly found globally and aligns well with regional iron-rich deposits.
