Large genuine Mongolian fluorite semiprecious gemstone pendant bead for jewelry making. Drilled on the top - see picture.
Pictures are from both sides of the bead.
I am not able to find a good non-commercial info source for Mongolian fluorite so I borrowed this:
"Mongolia was the fifth largest producer of fluorspar in 2003 accounting for 4.2% of the world's production. Some 860.000 tonnes of fluorspar are mined each year, producing over 120.000 tonnes of fluorspar concentrate, mostly for export. Fluorite mineralization is widespread throughout Mongolia in rocks of late Paleozoic to late Mesozoic age. The major period of formation of economically important mineralization took place during late Mesozoic to late Jurassic and early Cretaceous time periods. The fluorite mineralization occurs in two economic types: epithermal vein and metasomatic ore bodies.
Late Mesozoic fluorite mineralization is associated with rare earth and lead-zinc mineralization but not in economic quantities. Three major fluorite provinces have been defined in Mongolia, the North Mongolia, Trans-Mongolian, and South Mongolian fluorite provinces, with the Trans-Mongolian province having the largest reserves and being the most actively mined."
