Amber vs Aurichalcite
Amber and Aurichalcite are easy to confuse. Amber is harder (Mohs 2.5) than Aurichalcite (Mohs 1–2), so Amber will scratch Aurichalcite and not the other way round. A fingernail (Mohs 2.5) scratches it easily. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Amber and Aurichalcite
- Amber is harder (Mohs 2.5) than Aurichalcite (Mohs 1–2), so Amber will scratch Aurichalcite and not the other way round. A fingernail (Mohs 2.5) scratches it easily.
- Streak color differs: Amber leaves a white streak on unglazed porcelain, Aurichalcite leaves pale blue-green.
- Aurichalcite feels noticeably heavier for its size (specific gravity 3.6–3.9 versus 1.1 for Amber).
- Hold a thin edge to the light: Amber is transparent, Aurichalcite is Translucent.
- They overlap in green and blue, but Amber also comes in yellow, orange, brown, and red.
- Well-formed crystals give it away: Amber is amorphous, Aurichalcite is Monoclinic.

Which is more valuable?
Amber is usually the more valuable of the two: a typical collector specimen runs about $100 against $20 for Aurichalcite, and premium Amber can reach $5000 or more.
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 Aurichalcite
Aurichalcite is a hydrated zinc copper carbonate, (Zn,Cu)5(CO3)2(OH)6, that forms as a secondary mineral in the weathered, oxidized portions of zinc and copper ore bodies. It typically appears as delicate, pale blue-green sprays of needle-like crystals with a distinctly pearly luster. The name derives from Greek words for gold and copper, an old and somewhat misleading reference to brass-like alloys rather than the mineral's actual color.
Amber vs Aurichalcite FAQ
Is Amber the same as Aurichalcite?
No. Amber is a organic gem while Aurichalcite is a mineral. Amber is harder (Mohs 2.5) than Aurichalcite (Mohs 1–2), so Amber will scratch Aurichalcite and not the other way round. A fingernail (Mohs 2.5) scratches it easily.
How can you tell Amber from Aurichalcite?
