No data

Comments:

Fluorescence of Hauyne of Laacher See, Eifel, Germany, has been described by Gunnell in 1939 (probably in The Mineralogist).

As the sulfide replaces the sulfate in Hauyne it loses its fluorescence and becomes opaque and is the classic Lazurite. To be real Lazurite, it must be sulfide dominant and none have ever been found, so all lazurite is hauyne! (http://www.mindat.org/photo-586625.html)

In practice: darker samples are considered as the variety Lazurite.
