Pewter vs Sterling Silver
Pewter and Sterling Silver are easy to confuse because both are metals & alloys. Both sit near Mohs 2.5, 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 Pewter and Sterling Silver
- Both sit near Mohs 2.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
