Main Activator(s) and spectrum:

Most Common Activator: S₂^-

Peaks in the spectrum (nm):

S^2- repl.[SO₄]^2- : band centered around 680 nm with ondulations at: 516, 563, 580, 604, 621, 644, 666, 691, 715, 745nm

Comments on activators and spectra:

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

Form of the spectrum: typical wavelet of S^2- upon a large band.

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.
