Extremely variable colour stone widespread in the world. Unfortunately his low hardness (4 from the Mohs scale) does not allow the use in the jewellery industry, except for necklaces or pendants. Although is soft, has a nice brilliancy. Quite often it react at long wave with a nice fluorescence likely due to Uranium and rare earths, sometimes to organic inclusions (hydrocarbons). Some material is thermo luminescent; some is phosphorescent.
Nevertheless is a fascinating stone; often zoned of various colours, while is rare to find flawless in big size.
This pink fluorite at the loupe there are very tiny inclusions.Is considered the queen of the fluorites,especially among minerals collectors,in fact this material is found in the glacier of Monte Bianco,in the italian side.
