Azurite is a carbonate mineral formed in the oxidized portions of copper deposits.  Its crystals can take over 145 different forms and its color varies from a beautiful azure blue to a much darker blue-black.  Azurite and malachite often occur in the same formations.

Malachite is a shining copper ore with swirling islands of rich green color. Used since ancient Egyptian times as pigment for cosmetics, dyes and paints, malachite's primary use today is still ornamental. Popularized in modern times in 19th century Europe, it was worn as protection against the "evil eye." Much of today's fine malachite is mined in the Congo.
