Calcite
Calcite is one of the most common minerals in Earth's crust, with a chemical formula of
CaCO3.
It can be easily confused with quartz or selenite, but hardness, cleavage, crystal form, and reaction to acids help to positively identify it. It comes in many colors and crystal habits. So-called "Mexican onyx" is actually colorfully banded calcite rock (travertine).
