Amber vs Pyrophyllite
Amber and Pyrophyllite are easy to confuse. Amber is harder (Mohs 2.5) than Pyrophyllite (Mohs 1.5), so Amber will scratch Pyrophyllite 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 Pyrophyllite
- Amber is harder (Mohs 2.5) than Pyrophyllite (Mohs 1.5), so Amber will scratch Pyrophyllite and not the other way round. A fingernail (Mohs 2.5) scratches it easily.
- Pyrophyllite feels noticeably heavier for its size (specific gravity 2.8 versus 1.1 for Amber).
- Hold a thin edge to the light: Amber is transparent, Pyrophyllite is translucent.
- They overlap in yellow, brown, and green, but Amber also comes in orange, red, and blue and Pyrophyllite also comes in white and gray.
- Well-formed crystals give it away: Amber is amorphous, Pyrophyllite is monoclinic.

Which is more valuable?
Amber is usually the more valuable of the two: a typical collector specimen runs about $100 against $30 for Pyrophyllite, 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 Pyrophyllite
Pyrophyllite is a very soft aluminum silicate that closely resembles talc, with a pearly luster and a greasy feel. It typically forms foliated, fibrous, or radiating aggregates in metamorphic and hydrothermally altered rocks.
Amber vs Pyrophyllite FAQ
Is Amber the same as Pyrophyllite?
No. Amber is a organic gem while Pyrophyllite is a silicate mineral. Amber is harder (Mohs 2.5) than Pyrophyllite (Mohs 1.5), so Amber will scratch Pyrophyllite and not the other way round. A fingernail (Mohs 2.5) scratches it easily.
How can you tell Amber from Pyrophyllite?
