Chrysocolla vs Malachite
Chrysocolla and Malachite are easy to confuse because both are minerals. Malachite is harder (Mohs 4) than Chrysocolla (Mohs 2.5), so Malachite will scratch Chrysocolla and not the other way round. A copper coin (Mohs 3.5) scratches it, but a fingernail does not. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Chrysocolla and Malachite
- Malachite is harder (Mohs 4) than Chrysocolla (Mohs 2.5), so Malachite will scratch Chrysocolla and not the other way round. A copper coin (Mohs 3.5) scratches it, but a fingernail does not.
- Streak color differs: Chrysocolla leaves a white to pale blue streak on unglazed porcelain, Malachite leaves pale green.
- Luster is different: Chrysocolla is vitreous while Malachite is silky.
- Malachite feels noticeably heavier for its size (specific gravity 4 versus 2.2 for Chrysocolla).
- Hold a thin edge to the light: Chrysocolla is translucent, Malachite is opaque.
- They overlap in green, but Chrysocolla also comes in blue and Malachite also comes in multicolored.
- Well-formed crystals give it away: Chrysocolla is orthorhombic, Malachite is monoclinic.
