Azurite - Chessy-les-Mines, Beaujolais, France - Height: 3.2 cm - Width: 3.1 cm- 28 g

Azurite is a deep blue copper mineral obtained from oxidized copper ore deposits. Renowned for its rich, vivid blue hues, it often forms striking crystal clusters or massive formations. The example from Chessy-les-Mines in France is significant since this locality is historically notable and highly regarded among mineral collectors for its exceptional azurite specimens. Azurite typically crystallizes in monoclinic systems, showing tabular or prismatic crystals, and sometimes forms botryoidal or stalactitic shapes. Its intense blue color comes from the presence of copper ions. Aside from its use as a gemstone and ornamental stone, azurite has historically been ground into pigment for paints. It often forms alongside malachite, another copper carbonate mineral, offering collector appeal when presented together. The dimensions and weight suggest a hand specimen ideal for display or educational purposes, illustrating the fascinating beauty of secondary copper minerals.
