A very common and widespread mineral with highly variable forms and colours. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhombohedral cleavage in most varieties.

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3). It is a very common mineral, particularly as a component of limestone. Calcite defines hardness 3 on the Mohs scale of mineral hardness, based on scratch hardness comparison.

La calcita es un mineral formado por carbonato cálcico (CaCO 3), de la clase 5 de la clasificación de Strunz, los llamados minerales carbonatos y nitratos. A veces, se usa como sinónimo caliza, aunque es incorrecto pues esta última es una roca, no un mineral. Su nombre viene del latín calx, que significa cal viva.
