Azurite Gemstone Information. Azurite is a rare variety of gemstone-quality copper ore. Azurite is one of two basic copper carbonate minerals (malachite is the other). Azurite is rarer than malachite and is considered more valuable. Azurite gets its name from the Persian word 'lazhward', which refers to its distinctive, vivid blue color.
Azurite can be easily identified by its unique azure blue color. It is fairly soft and usually a simple scratch test can usually distinguish azurite from other gemstones. It is often found with malachite, but since malachite is obviously green in color, there is not much difficulty in separating the two.
