Dargaite

Dargaite is a rare mineral with formula BaCa₁₂(SiO₄)₄(SO₄)₂O₃. It is the barium-analogue of nabimusaite, also differing from it in the lack of fluorine. It is one of many recently approved new minerals coming from the Hatrurim complex. Dargaite, as nabimusaite, is trigonal (space group R-3m).^[1][2]
