Fluorite (also called fluorspar) is a halide mineral composed of calcium fluoride, . It is an isometric mineral with a cubic habit, though octahedral and more complex isometric forms are not uncommon. Crystal twinning is common and adds complexity to the observed crystal habits.
In 1852 fluorite gave its name to the phenomenon of fluorescence, which is prominent in fluorites from certain locations, due to certain impurities in the crystal. Fluorite also gave the name to its constitutive element fluorine.
This stone was absolutely perfect and just what I spent over a year and a half looking for! Super unique, my jewler was very impressed and it looks incredible in my updated wedding set!!! A+++
How lovely to hear!
