Shungite vs Sterling Silver
Shungite and Sterling Silver are easy to confuse. Both sit near Mohs 3.5, 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 Shungite and Sterling Silver
- Both sit near Mohs 3.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Streak color differs: Shungite leaves a black streak on unglazed porcelain, Sterling Silver leaves silver-white.
- Both look metallic, so compare color, tarnish and weight rather than shine.
- Sterling Silver feels noticeably heavier for its size (specific gravity 10.3 versus 1.9 for Shungite).
- They overlap in black and gray, but Sterling Silver also comes in white.
