One form of fluorite, antozonite, has a smell suggestive of fluorine when crushed.
2.
In 2012, a study reported detection of trace quantities ( 0.04 % by weight ) of diatomic fluorine in antozonite.
3.
The existence of gaseous fluorine in crystals, suggested by the smell of crushed antozonite, is contentious; a 2012 study reported the presence of 0.04 % by weight in antozonite, attributing these inclusions to radiation from the presence of tiny amounts of uranium.
