Azurite has a dark, rich blue color - its formula, Cu3(CO3)2(OH)2, is very close to malachite. The blue color of azurite is from Cu+, while the green color of malachite is from Cu+2. Azurite & malachite almost invariably occur together, and are telling indicators of copper in the field, even in very small quantities.
