The name celestina derives from the Latin word caelestis, which means celestial, derived in turn from caelum, sky. Celestine, or celestite, is a mineral made up of strontium sulfate (SrSO4). The mineral gets its name from its delicate blue color. Along with stronzianite, celestine is the main source of the element strontium, commonly used in fireworks and various metal alloys. In fact, its dust emits a bright red glow when burned. It is also used to produce glass, ceramics, paint and rubber and in jewelry. It is found in various parts of the world, usually in small quantities. Pale blue crystal specimens are found in Madagascar. White and orange variants have been found in Bristol, UK, where celestine was mined for commercial purposes until the mid-20th century.
