What it is confused with
Plastic, dyed stone and reconstituted malachite. Natural malachite has concentric bands, feels cold and is heavy for its size.
Banded bright and dark green
Malachite crystal meaning
Malachite is copper carbonate hydroxide (Cu₂CO₃(OH)₂), banded bright and dark green, rated 3.5–4 on the Mohs scale. Traditionally, it is associated with transformation and refusing to repeat a pattern — attributed, not demonstrated.

Worth knowing
Contains copper and is toxic as dust — polished stone is safe to handle, but it should never be ground, licked or put in drinking water.
History
Ground into eye paint in ancient Egypt and used as a green pigment through the Renaissance.

Buying
Buying Malachite: fakes, value and treatments
What decides the price
Bold, sharply contrasted banding. Malachite is inexpensive as beads but prized in large decorative slabs.
Where it is used
The Malachite Room of the Winter Palace in St Petersburg is faced with Ural malachite veneer.
A less familiar fact
Malachite is a copper carbonate; its dust is toxic, so it is cut wet and should never be used for "crystal water".
Practical
Caring for Malachite
How to clean it
Dry or barely damp cloth only. Never ultrasonic, never acid — and never grind it, the dust is toxic.
How to tell it is real
Reconstituted malachite — powder bound in resin — is widespread. Natural banding is irregular and never repeats; reconstituted material is suspiciously uniform.
How hard is Malachite?
Malachite is soft and, as a carbonate, reacts with acids, household cleaners included. Its dust is toxic, so it is never sanded or repolished at home. Among the stones in this reference, the next softer is Pearl (2.5–4.5) and the next harder Fluorite (4).
Malachite, at 3.5–4, is harder than 4 of the other 42 stones here and softer than 38.
Primary source
What Pliny the Elder wrote about Malachite
“Molochitis is not transparent, being of a deeper green, and more opaque than smaragdus; its name is derived from the mallow, which it resembles in colour.”
Pliny the Elder, The Natural History, translated by John Bostock and H. T. Riley (London: H. G. Bohn, 1855–57), book 37, chapter 36 — read the original text.
Molochitis is generally identified with malachite, which takes its name from the same Greek word for mallow. Who Pliny was and why we quote him →
Traditional associations
Malachite is traditionally associated with transformation and refusing to repeat a pattern. Chakra in crystal practice: Heart, Solar Plexus. Element: Earth.
Questions about Malachite
What is Malachite made of?
Copper carbonate hydroxide (Cu₂CO₃(OH)₂), crystallizing in the monoclinic system.
Where does Malachite come from?
DR Congo, Russia, Zambia, Australia.
Can Malachite be worn every day?
Not in a ring. At 3.5–4 on the Mohs scale it is better kept for pendants, earrings or display, away from acids, including household cleaners.
