This ethereal mineral would be a favorite of lady Galadriel, if she ever has to pick one. Luckily you don't need to be a high elf to appreciate the pale blue radiance of this mineral. It will bring a complex brilliance to any space whether hobbit hole or cubicle. 

Celestite is a mineral composed of strontium sulfate (SrSO4). Its name is derived from Latin word Caelestis, meaning "celestial", which was inspired by the crystals’ well-known shades of sky blue. This mineral can occur in geodes as crystals. Celestite can also occur as fibers in sedimentary rock: river, streams, and ocean beds. The crystals are also often found growing alongside Gypsum, Anhydrite and Halite. Celestite is found worldwide in small quantities. The pale blue specimens that the name is derived from are found in Madagascar and Sicily, Italy. It can also occur as colorless, white, pale blue, pink, pale green, pale brown, and black. Orange specimens have been found in Ontario, Canada.

According to metaphysics: Associated with celestial beings, Celestite is strongly connected to divine energy and cosmic supernatural forces. As the result, this gem is best used for pursuing spiritual strength. Celestite also promotes discernment or higher spiritual awareness. This makes the stone good for gaining understanding and promoting inner peace.
