It crystallizes in the tetragonal crystal system (space group I4/m).
Key properties: Mohs hardness 4; specific gravity 4.171; White streak; Vitreous luster; optically uniaxial.
IMA symbol Bav, IMA status: approved, named in 2014.
Found in barium-rich low-temperature skarn related to a porphyritic quartz monzonite stock.
It is found associated with Alstonite, baryte, celsian, diopside, fresnoite, mica, suzukiite, walstromite, witherite, minerals of the cerchiaraite group...
