Chemically composed of Cu2CO3(OH)2, Malachite is a mineral of copper carbonate hydroxide known for its awesome green color which does not easily fade when exposed to the sun for a long time. Malachite forms in the oxidizing zone above the copper deposit at the shallow depths of the earth. It develops in limestone where a suitable sub surface chemical environment that promotes the carbonate minerals’ formation is available. The mineral solidifies from the descending solutions and in the stalactites and botryoidal coatings in the inter-granular spaces, caverns, cavities, and fractures of porous rocks.
The main captivating physical property of Malachite is its green color. The stone is available in different shades such as bright green, pastel green, dark green, blackish green and many others. Normally, Malachite does not form into crystals. But in rare cases, it can form crystals in acicular to tabular shape with a light green color.
The crystallized variants have vitreous to adamantine luster and are also translucent. On the other hand, a non-crystalline type of Malachite is available in dull to earthy luster and is opaque in appearance. The former has very bright luster while the latter is silky. There are some specimens that are massive and fibrous. Malachite is a soft mineral that on the Mohs scale has a hardness of 3.5 to 4.0, with a high specific gravity of 3.6 to 4.0. When the stone comes in contact with cold diluted hydrochloric acid, it produces effervescence and is also heat sensitive. It has a perfect cleavage in one direction, while it is fair in the second direction. Malachite displays a light green hue but does not fluoresce. With an optical character of Biaxial (-), it has weak dispersion, 0.2540 double refraction, and a refractive index of a=1.655, b=1.875 and g=1.909.
Malachite is a very useful mineral both for the ancient era and modern era. Initially, it was a very important source of copper metal but today its use has widened. But as more affordable means of producing copper ore have been introduced, it is no longer mainly used to produce copper. Malachite has been a very good material for molding and carving for many years till now. The contemporary world’s lapidaries and jewelers widely use it to produce beads and cabochons which in combination with other materials can be used to make quality jewelry. However, because of its low hardness, it can only be used to make items that receive minimal impact. Malachite retains its green color for many years. This is why it can be ground and mixed with other ingredients to produce paints.

It is believed that the security and protection of the children of the possessors are guaranteed. Malachite is used to surround oneself with the healing power of the green nature.
