Earth Treasures: Celestite

By Chisom Ibemere

Celestite is a mineral composed of strontium sulfate which is named for its occasional delicate blue color. Celestine and the carbonate mineral strontianite are the principal sources of the strontium element, commonly used in fireworks and in various metal alloys.

The name “Celestite” is derived from the Latin word “caelestis,” which means celestial or heavenly, due to its pale blue color reminiscent of the sky. Celestite was first discovered in the late 18th century in the British county of Derbyshire. It is also found in various other locations around the world.

Celestite is commonly found in sedimentary rocks which is often associated with evaporite deposits. It is found in countries such as Madagascar, Mexico, the United States, Poland, and Brazil.

Celestite is a mineral that belongs to the group of sulfate minerals. It typically occurs as prismatic crystals or in nodular and fibrous forms. Celestite crystals are usually pale blue, but can also be colorless, white, or gray. It has a vitreous to pearly luster and a Mohs hardness of 3 to 3.5.

Celestite has various uses and applications. One of its major uses is as a source of strontium, an element used in the production of fireworks, ceramics, and glass. It is also utilized in the manufacturing of specialized lenses for certain astronomical telescopes due to its optical properties.

In the field of crystal healing and metaphysical practices, Celestite is believed to have calming and soothing energies, aiding in stress relief, relaxation, and improved communication.

The value of Celestite depends on factors such as size, quality, color, and crystal formation. It is considered a relatively affordable mineral, with prices varying among different sources and markets. Celestite is primarily valued for its use in the production of strontium and specialized lenses, as well as its metaphysical properties.
