It crystallizes in the cubic crystal system (space group I2_13).
Key properties: Mohs hardness 2.974; specific gravity 2.974.
IMA symbol Ver, IMA status: approved, named in 2017.
Found in fumarolic sublimates.
It is found associated with Ralstonite, hieratite, knasibfite, matteuccite, avogadrite, mallardite (Vesuvius); jakobssonite, anhydrite, leonardsenite, ralstonite, jarosite.
The mineral was named to honor French author Jules Verne (1828-1905), for his promotion of science. His Voyage au center de la Terre (1864).
