This specimen contains radiating fibrous malachite
on matrix, mined in Morocco. Fibrous malachite is an unusual form of malachite made up of slender prisms of tiny, fibrous needles. These needles merge to create sprays and fans of deep green color. Sometimes referred to as silky or velvet malachite, it's a very showy and displayable form of this forest green mineral.
The slight blue coloring to portions of the rock is caused by azurite.
Azurite and Malachite are known to form in union with each other, for their chemical makeup is very similar. In fact, the presence of more or less water in the location of formation, is enough to determine whether an abundance of malachite over azurite, or vise-versa, will accumulate.
These minerals tend to be found near copper deposits, which accounts for the colors the minerals display. This association of azurite and malachite on copper rich, iron oxide matrix was found near M'Cissi, Alnif, Tinghir Province, Souss-Massa-Draâ Region, Morocco.
