La malaquita es un mineral del grupo V (carbonatos) según la clasificación de Strunz, de fórmula química Cu2CO3(OH)2 (dihidróxido de carbonato de cobre (II)). Posee un 57,0% de cobre. Su nombre viene del griego malaqh, que significa ‘malva’, en alusión a su color verde. En la antigüedad era usada como colorante, pero hoy en día su uso es más bien como piedra semipreciosa. También se la usa como mena para la extracción de cobre. Los yacimientos más importantes de este mineral están en Colombia, República Democrática del Congo, Sudáfrica, Zimbabue, Rusia, Namibia, Hungría, Estados Unidos y China.
