Hematite vs Iron
Hematite and Iron are easy to confuse. Hematite is harder (Mohs 6) than Iron (Mohs 4), so Hematite will scratch Iron and not the other way round. A steel knife blade (Mohs 5.5) scratches it; a copper coin does not. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Hematite and Iron
- Hematite is harder (Mohs 6) than Iron (Mohs 4), so Hematite will scratch Iron and not the other way round. A steel knife blade (Mohs 5.5) scratches it; a copper coin does not.
- Streak color differs: Hematite leaves a red to reddish-brown streak on unglazed porcelain, Iron leaves gray to dark gray.
- Both look metallic, so compare color, tarnish and weight rather than shine.
- Iron feels noticeably heavier for its size (specific gravity 7.87 versus 5.3 for Hematite).
- They overlap in gray, but Hematite also comes in black and red and Iron also comes in brown.

About Hematite
Hematite is the most important iron ore mineral. Its name comes from the Greek word for blood, referring to its red streak.
About Iron
Iron is a gray metallic element and the base metal for steel. In everyday scans it may appear as wrought iron, cast iron, raw metal, hardware, tools, or rusty objects.
