Gold vs Pyrite
Gold and Pyrite are easy to confuse. Pyrite is harder (Mohs 6.5) than Gold (Mohs 2.5), so Pyrite will scratch Gold and not the other way round. A copper coin (Mohs 3.5) scratches it, but a fingernail does not. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Gold and Pyrite
- Pyrite is harder (Mohs 6.5) than Gold (Mohs 2.5), so Pyrite will scratch Gold and not the other way round. A copper coin (Mohs 3.5) scratches it, but a fingernail does not.
- Streak color differs: Gold leaves a golden yellow streak on unglazed porcelain, Pyrite leaves greenish-black.
- Both look metallic, so compare color, tarnish and weight rather than shine.
- Gold feels noticeably heavier for its size (specific gravity 19.3 versus 5 for Pyrite).

About Gold
Gold is a native metallic element prized for its rich yellow color, high density, malleability, and resistance to tarnish. In specimens it appears as nuggets, wires, leaves, grains, or crystalline masses, often associated with quartz veins or placer gravels.
About Pyrite
Pyrite, commonly known as 'fool's gold,' is an iron sulfide with a metallic luster and pale brass-yellow color. Despite its name, it has significant industrial uses.
