Azurite is a striking deep-blue copper carbonate mineral with the chemical formula Cu3(CO3)2(OH)2. Renowned for its vivid deep blue color, azurite derives its name from the Persian word lazhward, meaning “blue.” The intensity of its color and relative abundance make it a popular choice for collectors and lapidaries alike.
How Azurite Forms
Azurite forms in the oxidation zones of copper ore deposits when water containing carbon dioxide reacts with copper-rich minerals. This creates a secondary mineral layer that includes azurite and often its green cousin, malachite. Azurite is also one of the minerals mined to make copper metal. The two frequently occur together, as malachite forms when azurite undergoes further oxidation. It typically forms monoclinic crystals or massive, botryoidal aggregates.
Common Uses of Azurite
Historically, azurite was ground into a pigment for blue paints and dyes. However, its instability and tendency to turn green from oxidation led to its replacement by synthetic pigments. Today, azurite is primarily valued as an ore, a collector’s mineral, a semi-precious gemstone, and a tool for metaphysical practices. While relatively soft (3.5 to 4 on the Mohs scale of hardness), it is sometimes used in jewelry as cabochons or inlays.
