Azurite is a copper carbonate hydroxide mineral. It is best known for its characteristic deep blue to violet-blue color. The blue color, known as "azure," is like the deep blue evening skies often seen above deserts and winter landscapes. Malachite is another copper carbonate mineral that forms under conditions similar to azurite. These minerals are often found in the same deposit and are often intergrown with one another. This produces a material known as azurmalachite, which, when of high quality, can be used as a beautiful lapidary material. The most diagnostic property of azurite is it distinctive deep blue color. It is also soft with a Mohs hardness of only 3.5 to 4. So it flakes and fragments easily. It contains copper, which gives its blue color and a specific gravity of 3.7 to 3.9, which is exceptionally high for a non-metallic mineral Azurite also can slowly weather to malachite. This results in a lightening and greening of the gemstone's deep blue color. Store azurite jewelry in darkness, away from heat, and where air circulation is limited. This might be in a closed jewelry box or drawer. This item ships in a box for storage.
