Celestine or Celestite

Celestine, also known as celestite, is a mineral primarily composed of strontium sulfate. It typically displays a pale blue color, as seen in these polished stones, but can also appear in white, pink, or gray. Its name comes from the Latin term "caelestis," meaning "heavenly," evoking its soft blue hue. Discovered in the 18th century, celestine is commonly extracted from deposits in Madagascar, the United Kingdom, Poland, and the United States. Celestine is used in the manufacture of certain chemical products as well as a collector's item for its natural beauty.
