Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.
The malachite kingfisher (Corythornis cristatus) is a river kingfisher which is widely distributed in Africa south of the Sahara. It is largely resident except for seasonal climate-related movements. It is largely resident except for seasonal climate-related movements.

Botryoidal habit of gibbsite crystals. A botryoidal (/ ˌ b ɒ t r i ˈ ɔɪ d əl / BOT-ree-OY-dəl) texture or mineral habit, is one in which the mineral has an external form composed of many rounded segments, named for the Ancient Greek βότρυς (bótrus), meaning "a bunch of grapes". [1]
Siproeta stelenes (malachite) is a Neotropical brush-footed butterfly (family Nymphalidae). The malachite has large wings that are black and brilliant green or yellow-green on the upperside and light brown and olive green on the underside. It is named for the mineral malachite, which is similar in color to the bright green on the butterfly's ...
Citrine “A powerful gemstone crystal in a range of deep yellows, oranges, and yellow-cream-white, the citrine gemstone is said to bring abundance and wealth into one’s life,” Salzer says.
Like many other copper compounds, it also has been used as an algaecide, wood preservative and similar applications. It is a precursor to various catalysts and copper soaps. [3] Both malachite and azurite, as well as synthetic basic copper carbonate have been used as pigments. [10]
