Not quite all over the World, Fluorite - it's a northern hemisphere temperate & warm temperate species that can also be found in mountain zones in the sub-tropics (Himalayas, East Asia, N.Africa). There is some thought that it may be an exotic species in N.America (http://www.hmana.org/mothpix/exotics.htm, and http://www.inspection.gc.ca/english/...8origine.shtml).

hope this helps.

cheers,
