Nickel vs White Gold
Nickel and White Gold are easy to confuse because both are metals & alloys. Nickel is harder (Mohs 4) than White Gold (Mohs 3), so Nickel 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 Nickel and White Gold
- Nickel is harder (Mohs 4) than White Gold (Mohs 3), so Nickel 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: Nickel leaves a gray streak on unglazed porcelain, White Gold leaves white metallic.
- Both look metallic, so compare color, tarnish and weight rather than shine.
- White Gold feels noticeably heavier for its size (specific gravity 14 versus 8.9 for Nickel).
- They overlap in gray and yellow, but White Gold also comes in white.

Which is more valuable?
White Gold is usually the more valuable of the two: a typical collector specimen runs about $400 against $15 for Nickel, and premium White Gold can reach $8000 or more.
About Nickel
Nickel is a hard silvery metal used in plating, coins, stainless steel, batteries, magnets, jewelry alloys, and industrial alloys.
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.
Nickel vs White Gold FAQ
Is Nickel the same as White Gold?
No. Both are metals & alloys, but they are distinct species with different hardness, streak or luster. Nickel is harder (Mohs 4) than White Gold (Mohs 3), so Nickel will scratch White Gold and not the other way round. A copper coin (Mohs 3.5) scratches it, but a fingernail does not.
How can you tell Nickel from White Gold?
Nickel is harder (Mohs 4) than White Gold (Mohs 3), so Nickel 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: Nickel leaves a gray streak on unglazed porcelain, White Gold leaves white metallic. Both look metallic, so compare color, tarnish and weight rather than shine.
