Celestite (also known as Celestine) is a strontium sulfate mineral, named for its occasional delicate blue color. It occurs as crystals, as well as in compact, massive, and fibrous forms. Celestite is primarily found in sedimentary rocks and is often associated with gypsum, anhydrite, and halite. While it occurs worldwide, high-quality pale blue crystals are especially notable from Madagascar.
The famous Madagascar locality, discovered in 1967, produces around 15 tons annually. It lies near the village of Sakoany on the western banks of the Betsiboka River. The celestine-bearing layer forms a lens up to 30 meters thick, between crinoidal limestones and sandy greywacke from the Late Cretaceous. Mining involves digging shafts up to 15 meters (50 feet) deep. Celestite occurs mainly in two forms: geodes up to 60 cm in diameter and crystal clusters up to 15 cm across.
