Ilmenite vs Titanium
Ilmenite and Titanium are easy to confuse. 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 Ilmenite 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: Ilmenite leaves a black to brownish red streak on unglazed porcelain, Titanium leaves silver-gray.
- Both look metallic, so compare color, tarnish and weight rather than shine.

Which is more valuable?
Titanium is usually the more valuable of the two: a typical collector specimen runs about $40 against $35 for Ilmenite, and premium Titanium can reach $500 or more.
About Ilmenite
Ilmenite is an iron titanium oxide and the most important ore of titanium. It typically forms black, weakly magnetic, metallic to submetallic grains and tabular crystals in igneous rocks and heavy mineral sands.
About Titanium
Titanium is a strong, lightweight gray-silver metal used in jewelry, watches, tools, aerospace parts, medical hardware, and performance equipment.
