Stainless Steel vs Tungsten
Stainless Steel and Tungsten are easy to confuse because both are metals & alloys. Tungsten is harder (Mohs 7.5) than Stainless Steel (Mohs 5.5), so Tungsten will scratch Stainless Steel and not the other way round. It is about as hard as window glass: a knife barely marks it, while a steel file (Mohs 6.5) will. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Stainless Steel and Tungsten
- Tungsten is harder (Mohs 7.5) than Stainless Steel (Mohs 5.5), so Tungsten will scratch Stainless Steel and not the other way round. It is about as hard as window glass: a knife barely marks it, while a steel file (Mohs 6.5) will.
- Streak color differs: Stainless Steel leaves a gray to silver-gray streak on unglazed porcelain, Tungsten leaves gray.
- Both look metallic, so compare color, tarnish and weight rather than shine.
- Tungsten feels noticeably heavier for its size (specific gravity 19.25 versus 7.9 for Stainless Steel).

About Stainless Steel
Stainless steel is a silvery iron-based alloy commonly used in watch bands, rings, tools, cookware, and hardware. It is not a natural mineral specimen, but it is an in-scope visible material for StoneSnap when a scan clearly shows a metallic manufactured object.
About Tungsten
Tungsten is an extremely dense gray metal used in rings, weights, tools, electrodes, cutting materials, and high-temperature applications.
Stainless Steel vs Tungsten FAQ
Is Stainless Steel the same as Tungsten?
No. Both are metals & alloys, but they are distinct species with different hardness, streak or luster. Tungsten is harder (Mohs 7.5) than Stainless Steel (Mohs 5.5), so Tungsten will scratch Stainless Steel and not the other way round. It is about as hard as window glass: a knife barely marks it, while a steel file (Mohs 6.5) will.
