Fluorite
Fluorite or fluorspar
It is calcium fluoride (CaF2) which crystallizes into beautiful regular cubes, generally colored dark purple, yellow or green, more rarely red, pink or clear.
It is found in volcanic rocks.
Fluorite is a raw material whose addition facilitates the fusion of metals.
Colorless fluorite is used in the manufacture of optical lenses.
