From the White Knob quarry in the San Berardino Mts. CA, remarkable examples of orange or yellow-orange fluorescing wollastonite SW in blocky sections with orange-red fl. calcite SW and also red-fluorescing feldspar (species unidentified) of unusually high brightness. Information and help from Howard Brown and Lyman Hayes. Activator: Mn with Pb as coactivator?? Activator: probably Mn2+ substituting to Ca2+; also Fe3+ and Cr3+ found (Gaft).

In Jakobsberg, Sweden, wolastonite and margarosanite replace barysilite (see picture by Kjell Gatedal in bibliography )

Main Activator(s) and spectrum:

Most Common Activator: Mn2+

Other activators:            Cr3+ , Fe3+ ,

Peaks in the spectrum (nm):

Mn2+I repl. Ca2+I : 555-560nm

Mn2+II repl. Ca2+II  : 580nm  

Mn2+III repl. Ca2+III : 603, 640nm

Fe3+ repl. Si4+ : 690-700nm

Cr3+ : narrow R-lines at 720nm + 794 - 840nm broad band

Cr3+II : 794nm

Cr3+III : 840nm

Comments on activators and spectra:

Steady-state luminescence of wollastonite has been previously studied and luminescence of Mn2+, Fe3+ and supposedly Cr3+ has been proposed (Min’ko et al. 1978). (Gaft)
