Key Differences
Azurite is a copper carbonate mineral known for its vibrant deep blue color. It forms in the oxidation zones of copper ore deposits and is often found alongside malachite. Its blue hue comes from its chemical composition and crystal structure, making it a popular choice for pigments and ornamental stones. Malachite, on the other hand, is a green copper carbonate hydroxide mineral. It typically forms in the same environments as azurite, and the two minerals often occur together.
Azurite and malachite can sometimes transition into one another through chemical weathering processes. Azurite often alters to malachite over time when exposed to weathering conditions, resulting in specimens that exhibit both blue and green colors.
Both minerals have been valued since ancient times, but their primary distinction lies in their colors and specific uses. Azurite is prized for its striking blue color in jewelry and pigments, whereas malachite is appreciated for its intense green color and unique banding patterns in decorative objects and jewelry.

Azurite
Used in jewelry and as ornamental stones.
The museum displayed a beautiful azurite carving.
Malachite
Malachite is a copper carbonate hydroxide mineral, with the formula Cu2CO3(OH)2. This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.
Azurite
Azurite is a soft, deep-blue copper mineral produced by weathering of copper ore deposits. During the early 19th century, it was also known as chessylite, after the type locality at Chessy-les-Mines near Lyon, France.
Malachite
A light to dark green carbonate mineral, Cu2CO3(OH)2, used as a source of copper and for ornamental purposes.
Azurite
An azure blue vitreous mineral of basic copper carbonate, Cu3(CO3)2(OH)2, used as a copper ore and as a gemstone.
Malachite
(mineral) A bright green mineral, a basic copper carbonate, Cu2CO3(OH)2; one of the principal ores of copper.
Azurite
(mineral) A blue vitreous mineral; a basic copper carbonate, with the chemical formula Cu2+3(CO3)2(OH)2.
Malachite
A mild green colour, like that of the mineral.
Azurite
Blue carbonate of copper; blue malachite.
Malachite
Of a colour ranging from olive-taupe to a mild to deeply-rich (at times seemingly translucent) green, like that of the mineral which is present on oxidized copper.
Malachite
Native hydrous carbonate of copper, usually occurring in green mammillary masses with concentric fibrous structure.
