The mineral is named for its occasional delicate [[blue color]]. Celestine and the [[carbonate]] mineral [[strontianite]] are the principal sources of the [[chemical element|element]] [[strontium]], commonly used in [[fireworks]] and in various [[alloy|metal alloys]].

==Etymology==
Celestine derives its name from the [[Latin]] word ''caelestis'' meaning celestial<ref>{{cite dictionary |title=Celestine |dictionary=Collins English Dictionary |via=collinsdictionary.com |url=https://www.collinsdictionary.com/dictionary/english/celestine}}</ref> which in turn is derived from the Latin word ''caelum'' meaning sky, air, weather, atmosphere and heaven.<ref>{{cite dictionary |title=Celestial |date=24 April 2024 |dictionary=[[Merriam-Webster]] Dictionary |via=merriam-webster.com |url=https://www.merriam-webster.com/dictionary/celestial}}</ref>

==Occurrence==
Celestine occurs as [[crystal]]s, and also in compact massive and fibrous forms. It is mostly found in [[sedimentary]] rocks, often associated with the minerals [[gypsum]], [[anhydrite]], and [[halite]]. On occasion in some localities, it may also be found with [[sulfur]] inclusions.

The mineral is found worldwide, usually in small quantities. Pale blue crystal specimens are found in [[Madagascar]]. White and orange variants also occurred at [[Yate]], [[Bristol]], UK, where it was extracted for commercial purposes until April 1991.<ref>{{cite web |title=Beneath our feet |department=Discover [[Yate]]'s History |website=[[Yate]] Heritage Centre
|via=yateheritage.co.uk |url=http://www.yateheritage.co.uk/history-of-yate/beneath-our-feet.htm}}</ref>

The skeletons of the [[protozoan]] ''[[Acantharea]]'' are made of celestine, unlike those of other [[radiolarian]]s which are made of [[silicon dioxide|silica]].

In carbonate marine sediments, burial dissolution is a recognized mechanism of celestine precipitation.<ref>{{cite journal | last1=Baker |first1= Paul A. |last2= Bloomer |first2= Sherman H. |year= 1988 |title=The origin of celestite in deep-sea carbonate sediments | journal = Geochimica et Cosmochimica Acta | volume= 52 | issue =2 |pages=335–339 |bibcode=1988GeCoA..52..335B | doi = 10.1016/0016-7037(88)90088-9 }}</ref> It is sometimes used as a gemstone.<ref>{{cite book |first1=Roger |last1=Dedeyne |first2=Ivo |last2=Quintens |year=2007 |title=Tables of Gemstone Identification |publisher=Glirico |isbn= 978-90-78768-01-2 |page=174}} {{isbn|9078768010}}</ref>

==Geodes==
Celestine crystals are found in some geodes. The world's largest known [[geode]], a celestine geode {{convert|35|ft|m}} in diameter at its widest point, is located near the village of [[Put-in-Bay, Ohio]], on [[South Bass Island]] in [[Lake Erie]]. The geode has been converted into a viewing cave, [[Crystal Cave (Ohio)|Crystal Cave]], with the crystals which once composed the floor of the geode removed. The geode has celestine crystals as wide as {{convert|18|in|cm}} across, estimated to weigh up to {{convert|300|lb|kg}} each.

Celestine geodes are understood to form by replacement of [[alabaster]] nodules consisting of the [[calcium sulfate]]s gypsum or anhydrite. Calcium sulfate is sparingly soluble, but strontium sulfate is mostly insoluble. Strontium-bearing solutions that come into contact with calcium sulfate nodules dissolve the calcium away, leaving a cavity. The strontium is immediately precipitated as celestine, with the crystals growing into the newly formed cavity.<ref>{{cite journal |last1=Anenburg |first1=Michael |last2=Bialik |first2=Or |last3=Vapnik |first3=Yevgeny |last4=Chapman |first4=Hazel |last5=Antler |first5=Gilad |last6=Katzir |first6=Yaron |last7=Bickle |first7=Mike |year=2014 |title=The origin of celestine-quartz-calcite geodes associated with a basaltic dyke, Makhtesh Ramon, Israel |journal=Geological Magazine |volume=151 |issue=5 |pages=798–815 |doi=10.1017/S0016756813000800 |bibcode=2014GeoM..151..798A |s2cid=129529427 }}</ref><ref>{{cite journal |last1=Carlson |first1=Ernest |year=1987 |title=Celestite replacements of evaporites in the Salina Group |journal=Sedimentary Geology |volume=54 |issue=1–2 |pages=93–112 |doi=10.1016/0037-0738(87)90005-4 |bibcode=1987SedG...54...93C }}</ref><ref>{{cite journal |last1=Kile |first1=Daniel |last2=Dayvault |first2=Richard |last3=Hood |first3=William |last4=Hatch |first4=H.
