Azurite is popular with mineral collectors. They appreciate its deep blue monoclinic crystals, nodular habit with interesting structures, and representative examples of its botryoidal and stalactitic habits. Excellent specimens can sell for hundreds, thousands, or tens of thousands of dollars depending upon their quality and size.

The instability of azurite is a problem for collectors. If exposed to heat or high humidity, specimen surfaces will begin to weather to malachite. This causes a dull, faded or greenish appearance depending upon the severity of alteration. Valuable specimens are best stored in closed collection drawers where there is limited air circulation, darkness, and cool, stable temperatures.
