“Fluorescence Cage”: Visual Identification of HPHT-Treated Type I Diamonds Inga A. Dobrinets and Alexander M. Zaitsev HPHT- ... type I diamonds of various colors may exhibit unusually intense fluorescence at the facet edges and junctions. This effect, here named the “ ... or colorless type IIa HPHT-treated diamonds. This fluorescence pattern is believed to result from a high concentration of HPHT- ...

Baohong Yuan, Yuan Liu, Patrick M. Mehl, and Joseph Vignola The feasibility of using ultrasound to modulate fluorescence in a turbid medium is still in debate due to the difficulty of detecting the modulated signal. We have demonstrated a system that could detect the weak signals of ultrasound-modulated fluorescence (UMF) by using a broadband lock-in amplifi ... published Fri Nov 6, 2009.

... a bit different. More by chance, or rather as looking for leucophanite, I put it under the UV - no fluorescence of the blue mineral at all. This is most unusual for Tvedalen sodalites, ... as possible cancrinite at the Munich show, but took it for XRD: sodalite! Well, does anybody know, what causes fluorescence of sodalite and what needs to be present or absent to make it non-fluorescent? ...
