Interesting facts: Celestine is named after Latin "caelestis" - of the sky, alluding to the sky-blue colour commonly exhibited by its crystals.
Celestite is a synonym of celestine, so they refer to the same mineral. Celestine is the approved name for this crystal by the International Mineralogical Association though celestite is still very commonly used, even in mineralogical texts.
