Platinum vs White Gold
Platinum and White Gold are easy to confuse. Platinum is harder (Mohs 4.25) than White Gold (Mohs 3), so Platinum will scratch White 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 Platinum and White Gold
- Platinum is harder (Mohs 4.25) than White Gold (Mohs 3), so Platinum will scratch White Gold 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, White Gold leaves white metallic.
- Both look metallic, so compare color, tarnish and weight rather than shine.
- Platinum feels noticeably heavier for its size (specific gravity 18 versus 14 for White Gold).
- They overlap in gray, but White Gold also comes in white and yellow.

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 White Gold
White gold is a pale gold alloy made with white metals and often rhodium plated. It is common in rings, watches, necklaces, bracelets, and jewelry settings.
