Description: A transparent to translucent, often blue or purple mineral, commonly found in crystalline cubes in veins and associated with lead, tin, and zinc ores; hardness is 4 on Mohs scale; the principal ore of fluorine. Fluorite is the only mineral for which significant quantities of the important element fluorine can be obtained. Navigation basics; All controls; Orbit around. For business.
