What does fluorite smell like?

Fluorite is normally odourless. However there is one location, Wölsendorf in Bavaria where there mineral is radioactive and this causes inclusion of elemental Fluorine to occur in the crystals. On fracture chemical reactions between the air and this Fluorine cause the formation of "Ozone" (which smells of electric sparks). This variety of Fluorite is therefore called Antozonite or "Stinkspar" .

Also Fluorite crystals are sometimes oiled with mineral oils to make them appear more transparent for sale and these crystals can smell oily.
