Brass vs Gold
Brass and Gold are easy to confuse. Brass is harder (Mohs 3.5) than Gold (Mohs 2.5), so Brass 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 Brass and Gold
- Brass is harder (Mohs 3.5) than Gold (Mohs 2.5), so Brass 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: Brass leaves a yellow-gold to brass streak on unglazed porcelain, Gold leaves golden yellow.
- Both look metallic, so compare color, tarnish and weight rather than shine.
- Gold feels noticeably heavier for its size (specific gravity 19.3 versus 8.5 for Brass).
- They overlap in yellow, but Brass also comes in brown.

About Brass
Brass is a yellow-gold copper and zinc alloy often used in hardware, decorative objects, instruments, keys, fittings, and jewelry findings.
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.
