Comments:


This is a mineral of the sodalite family, more precisely a sulfide rich variety of Hauyne and should not be regarded as a separate species.

Lazurite is the blue component of the Lapis Lazuli, which is a Lazurite-Calcite-Pyrite rock.

From Lyadjvar, Pamir mountains, Tadjikistan. Fluoresces bluish under LW.

Lazurite of Ovalle Chile said to be thermoluminescente and phosphorescente by DeMent (see bibliography)
