Celestite
Global Mining Sites
Celestite is most commonly found In Libya, Egypt, Madagascar, Germany, Italy, Britain, Poland, Peru, Canada, Mexico and in the USA. The most commonly found colour of this stone is a sky-blue variety from Madagascar.
History
Also called ‘Celestine’, the mineral itself started being called ‘Celestite’ in 1798. This was sometime after the formal description of the element strontium in 1792.
Celestite derives its name from the Latin word caelestis meaning celestial, which in turn is derived from the Latin word caelum meaning sky or heaven. This refers to the lovely sky-blue colour of these stones.
In 1967, villagers started mining Celestite deposits and continued into the 1970s. Mining stopped for about 10 years, and didn’t resume until the early 1980s. Since then there has been a continuous supply of celestite crystal geodes and groups.
Appearance
The colour range of Celestite includes colourless, white, blue, yellow, orange and red.
It crystallizes both in tabular and prismatic forms and can be found in massive clusters and geodes. Celestite is a strontium sulfate and is very fragile with a hardness of only 3 to 3.5. It is found in combination with other minerals such as Albite, Halite and Anhydrite.
