How to Identify Malachite
Malachite is unmistakably green — from bright emerald crusts to dark banded masses — with a silky-to-dull luster and a pale green streak. It is soft (3.5–4, scratches with a knife easily) and fizzes gently in vinegar. Banded, rounded (botryoidal) surfaces are classic. Blue azurite alongside it is a bonus find from the same chemistry.
