Azurite is a mineral that is popular for its striking blue color. The spelling of the word Azurite is pronounced /əˈzjʊəraɪt/ or uh-zhoo-rahyt in IPA phonetic transcription. The word's spelling is derived from its color which shares similarities with the color Azure. Azurite can be found in copper ore deposits around the world and has been used for centuries as a pigment in art, and also for its decorative and healing properties. Due to its rarity, Azurite is highly valued in the jewelry market.
Azurite is a naturally occurring mineral that belongs to the carbonate class. It is primarily composed of copper and contains small amounts of other elements like carbon, oxygen, and hydrogen. The name "azurite" is derived from its deep azure blue color, which is its most distinguishing characteristic.
In terms of physical properties, azurite usually forms in masses or closely packed, tabular crystals. It has a relatively moderate hardness of around 3.5 to 4 on the Mohs scale, rendering it susceptible to scratches. Its lustrous, vitreous to silky sheen further enhances its appeal.
Azurite is commonly found in copper ore deposits and is considered to be a secondary mineral. It typically forms through the oxidation of copper sulfide minerals, often alongside malachite, another copper carbonate.
Due to its vibrant blue color, azurite has been used as a pigment throughout history, especially during the Renaissance. However, its pigment properties also make it relatively unstable when exposed to light and air, causing it to turn green over time.
In addition to its historical use as a pigment, azurite is treasured by collectors and lapidary artists for its aesthetic value. Its deep blue hue and striking crystal formations make it a sought-after gemstone and a popular choice for jewelry and ornamental purposes. Furthermore, azurite is of interest to mineralogists and geologists as a valuable source of research and study.

The word Azurite is derived from the Persian word lazhward, which means blue. This Persian term was derived from the Sanskrit term rajavarta, which translates to blue copper ore. Over time, the word was borrowed into Arabic as lazaward, and later into Medieval Latin as azureus. Eventually, azureus was anglicized into azurite.
