Hematite (hematite beads or tiles)

Hematite, α‑Fe₂O₃

AI-generated identification · may be incorrect

Likely polished, metallic gray hematite. Hardness 5–6.5 Mohs; metallic to submetallic luster; trigonal crystal structure; no prominent cleavage; specific gravity about 5.3. The image alone cannot confirm the material or distinguish natural hematite from manufactured imitation.

Physical properties

Formation & geological history

Hematite forms in iron-rich sedimentary deposits, hydrothermal veins, and through oxidation of iron-bearing minerals; deposits range from Precambrian banded iron formations to younger occurrences.

Uses & applications

Used as iron ore and pigment; polished beads and ornamental pieces are used in jewelry and collecting.

Geological facts

A useful identification test is its reddish-brown streak, though testing may damage a finished piece.

Field identification & locations

Natural hematite is common worldwide, including Brazil, Australia, China, and the United States. These uniform linked segments appear to be jewelry components, so verify material and magnetic response before identifying them as hematite.
