Celestite or Celestine (SrSO4) is a strontium sulfate. It forms in well-shaped crystals with a distinctive soft blue color. Crystals may be a solid color, but may also have lighter and darker color zones of blue. While pure Celestite is colorless, various impurities give this mineral a wider range of colors, especially the unique blue color but also orange, orange-brown, light brown, yellow, greenish-blue, gray. Celestite geodes with large blue crystals, from Madagascar are very popular among mineral collectors…

Celestite is isomorphous with Barite, and may partially replace it. One specimen may even be part Barite and part Celestite within a single crystal. Celestite is named from the Latin term caelestis, alluding to it typical celestial sky-blue color. The streak is white, the hardness is 3 - 3.5 and the luster is vitreous.
