Azurite - Malachite Children's bracelet | 4 mm
Azuriet – Malachiet Kinderarmband in 4 mm
Azurite
Azurite is an intense blue copper-bearing mineral often found in combination with malachite. Its striking colour ranges from deep royal blue to almost black-blue and is due to its high copper content. Azurite usually forms crystals, granular masses or nodular structures, and was used as a pigment as early as ancient times.
Major deposits of azurite include Namibia, Morocco, Australia, Mexico and the United States. The mineral is formed by the oxidation of copper ores in the upper layers of deposits, often together with malachite. Its chemical formula is Cu₃(CO₃)₂(OH)₂ and its hardness is between 3.5 and 4 on the Mohs scale.
