Likely metallic ore specimen

Undetermined; the silvery, reflective surface may indicate specular hematite (Fe₂O₃), but the image is insufficient for reliable identification.

AI-generated identification · may be incorrect

Small, angular piece with a silvery-gray metallic sheen and brown, rough sides. If specular hematite, hardness is about 5.5–6.5 Mohs, with a metallic-to-submetallic luster and trigonal crystal structure; streak testing would help distinguish it from other ores.

Physical properties

Formation & geological history

If hematite, it forms through oxidation or precipitation in sedimentary, hydrothermal, or metamorphic settings; specimens occur across a wide range of geological ages.

Uses & applications

Hematite is a major iron ore and is also used as pigment and in jewelry; this unverified small specimen has mainly educational or collecting interest.

Geological facts

A reddish-brown streak is characteristic of hematite, even when its surface appears steel-gray.

Field identification & locations

Common hematite sources include Brazil, Australia, and the Lake Superior region. Confirm identification with a streak test on unglazed porcelain and, if possible, hardness and density tests.
