Celestine or celestite is a mineral composed of strontium sulfate.
It is named because of its blue color. Celestine and the carbonate mineral strontianite are the main sources of the element strontium.

Celestine is mostly found in sedimentary rocks, often associated with gypsum, anhydrite and halite minerals.

This mineral is found all over the world, often in small amounts,Iran is one of the places where this mineral is found in high quality.
