Amber vs Sulfur
Amber and Sulfur are easy to confuse. 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 Amber and Sulfur
- Both sit near Mohs 2.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Streak color differs: Amber leaves a white streak on unglazed porcelain, Sulfur leaves white to pale yellow.
- Sulfur feels noticeably heavier for its size (specific gravity 2.07 versus 1.1 for Amber).
- They overlap in yellow, brown, and green, but Amber also comes in orange, red, and blue.
- Well-formed crystals give it away: Amber is amorphous, Sulfur is orthorhombic.

About Amber
Amber is fossilized tree resin, typically 30-90 million years old. It often contains preserved insects and plants, providing windows into prehistoric life.
About Sulfur
Sulfur is a native element famous for its bright yellow color. It forms blocky to dipyramidal crystals and earthy crusts around volcanic vents, hot springs, and salt domes, and has a distinctive resinous luster.
