Name:
Tentatively named latialite in 1803 by Carlo Giuseppe Gismondi for the locality at Campagna (Latium) without formal publication. Named in 1807 by Tønnes Christian Bruun de Neergaard in honor of Abbé Rene Just Haüy [February 28, 1743 Saint-Just-en-Chausse, France - June 1, 1822 Paris, France], "Father of Crystallography". Haüy was a Roman Catholic Priest and curator of the Muséum National d'Histoire Naturelle in Paris. Haüy devised and sold wooden crystal models which were highly prized internationally, both among his contemporaries as well as today. Named berzeline in 1831 by Louis Albert Necker de Saussiere in honor of Jöns Jakob Berzelius. The mineral was temporarily name hauynite by James Dwight Dana in 1868.
Sodalite Group.Ideally the two sodalite cages in Haüyne's unit cell contain Na3CaSO4
Pale-coloured varieties are easily confused with nosean and darker ones are the variety Lazurite.
