Platinum vs Silver
Platinum and Silver are easy to confuse because both are native elements. Platinum is harder (Mohs 4.25) than Silver (Mohs 2.75), so Platinum will scratch Silver 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 Platinum and Silver
- Platinum is harder (Mohs 4.25) than Silver (Mohs 2.75), so Platinum will scratch Silver and not the other way round. A copper coin (Mohs 3.5) scratches it, but a fingernail does not.
- Streak color differs: Platinum leaves a steel gray to silver-white streak on unglazed porcelain, Silver leaves silver white.
- Both look metallic, so compare color, tarnish and weight rather than shine.
- Platinum feels noticeably heavier for its size (specific gravity 18 versus 10.5 for Silver).
- They overlap in gray, but Silver also comes in white.

About Platinum
Platinum is a rare native metallic element with a silvery to steel-gray color, very high density, and strong resistance to corrosion. In nature it occurs as small grains, flakes, and nuggets rather than well-formed crystals, often within ultramafic rocks or placer gravels.
About Silver
Silver is a native metallic element with a bright silver-white color, high density, and excellent malleability. In specimens it appears as wires, dendrites, leaves, and crystalline masses, though exposed surfaces usually tarnish to dark gray.
Platinum vs Silver FAQ
Is Platinum the same as Silver?
No. Both are native elements, but they are distinct species with different hardness, streak or luster. Platinum is harder (Mohs 4.25) than Silver (Mohs 2.75), so Platinum will scratch Silver and not the other way round. A copper coin (Mohs 3.5) scratches it, but a fingernail does not.
