Celestite occurs as crystals, and also in compact massive and fibrous forms. It is mostly found in sedimentary rocks, often associated with the minerals gypsum, anhydrite, and halite.

Gypsum is a very soft mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. // Chemical structure Gypsum from New South Wales, Australia Heating gypsum above approximately 150°C (302°F) partially dehydrates the mineral by driving off exactly 75% of the water contained in its chemical structure. ... Anhydrite is a mineral - anhydrous calcium sulfate, CaSO4. ... Halite is the mineral of sodium chloride, NaCl, commonly known as rock salt. ...

The mineral is found worldwide, usually in small quantities. Pale blue crystal specimens are found in Madagascar.
