Physical properties

Formation & geological history

Hematite forms through oxidation of iron-rich minerals and precipitation from iron-bearing waters; deposits occur in rocks spanning much of Earth’s history. The image does not reveal the beads’ exact source or whether they are natural hematite or a manufactured imitation.

Uses & applications

Hematite is an important iron ore and is also used for pigment and ornamental beads or jewelry.

Geological facts

A reddish-brown streak on unglazed porcelain is a useful hematite test; magnetic behavior varies, and strongly magnetic jewelry beads may be synthetic imitation material.

Field identification & locations

Natural hematite commonly occurs in banded iron formations and hydrothermal or weathering deposits worldwide. Identify beads by their heft, metallic appearance, and red-brown streak; visual inspection alone cannot confirm authenticity.
