Malachite is comprised of its constituent elements
(copper, carbon, oxygen and hydrogen) arranged
in the monoclinic system of crystal symmetry.
True crystals of malachite are rare. This mineral is
usually found in the form of botryoidal encrusting masses,
often in a fibrous radiating form.
Malachite (and Azurite, which is chemically similar)
are common secondary copper minerals that frequently
occur together. These are usually located in the oxidized
zones of copper deposits.
