CA91AI6: Relatively common in the eighties the Celestine samples from Machov had a great success in the collectible mineralogical world due both for their strict mineralogical interest and the esthetic appearance of the crystals, elongated and transparent, often with smoky shades and extraordinarily bright. They are currently considered as classics of mineralogy and there are few samples for collectors. To all this we must add that the Celestine has the unusual property of being phosphorescent (during 1-2 seconds)
