Polished hematite bead (probable)

Hematite, Fe₂O₃

AI-generated identification · may be incorrect

Small polished gray-black sphere with metallic to submetallic luster; hematite hardness is about 5–6.5 Mohs, with no prominent cleavage and a relatively high specific gravity (~5.3). The image alone cannot exclude magnetite or an industrial metal bead.

Physical properties

Formation & geological history

Hematite forms through oxidation in hydrothermal, sedimentary, and metamorphic environments, ranging from Precambrian deposits to modern weathering zones. Polishing and drilling indicate human processing.

Uses & applications

Used for jewelry beads, ornamental objects, pigment, and as an iron ore; it has little value as a tiny common bead. Typical value is about $1–$10, or $10–$30 if unusually fine or confirmed natural.

Geological facts

A diagnostic streak test gives hematite a reddish-brown streak, unlike magnetite’s black streak. Hematite is usually weakly magnetic or nonmagnetic, whereas magnetite is strongly magnetic.

Field identification & locations

Common sources include Brazil, Australia, South Africa, and the United States. Test with an unglazed ceramic tile for streak and a magnet; strong attraction suggests magnetite or another iron-rich material.
