Stainless Steel vs Titanium
Stainless Steel and Titanium are easy to confuse because both are metals & alloys. Both sit near Mohs 5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Stainless Steel and Titanium
- Both sit near Mohs 5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Streak color differs: Stainless Steel leaves a gray to silver-gray streak on unglazed porcelain, Titanium leaves silver-gray.
- Both look metallic, so compare color, tarnish and weight rather than shine.
- Stainless Steel feels noticeably heavier for its size (specific gravity 7.9 versus 4.5 for Titanium).

Which is more valuable?
Titanium is usually the more valuable of the two: a typical collector specimen runs about $40 against $20 for Stainless Steel, and premium Titanium can reach $500 or more.
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 Titanium
Titanium is a strong, lightweight gray-silver metal used in jewelry, watches, tools, aerospace parts, medical hardware, and performance equipment.
Stainless Steel vs Titanium FAQ
Is Stainless Steel the same as Titanium?
No. Both are metals & alloys, but they are distinct species with different hardness, streak or luster. Both sit near Mohs 5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
How can you tell Stainless Steel from Titanium?
Both sit near Mohs 5.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Streak color differs: Stainless Steel leaves a gray to silver-gray streak on unglazed porcelain, Titanium leaves silver-gray. Both look metallic, so compare color, tarnish and weight rather than shine.
