2.5" Vibrant Green Malachite and Blue Azurite Association - China

Azurite and malachite are known to form in union with each other since their chemical makeup is very similar. In fact, the presence of more or less water in the location of formatio, is enough to determine whether an abundance of malachite over azurite, or vise-versa, will accumulate. These minerals tend to be found in oxidation zones of copper deposits, which accounts for the colors the minerals display.
