Celestine derives from the Latin term caelestis (celestial), referring to the color of the crystals. It occurs in tabular crystals that are colorless or slightly bluish, usually in limestones and sedimentary rocks, associated with gypsum, anhydrite, rock salt, and sulfur. It is also found in other habits: prismatic, acicular, tabular (red, white or blue), fibrous, coarse, granular and massive. Celestine may have a hydrothermal origin, in association with galena and sphalerite, or a sedimentary evaporitic origin from the evaporation of saline waters in association with sulfur, gypsum, aragonite, chlorides and other typical minerals.
