A large specimen, the agrellite displaying a bright pink under shortwave/midwave and a pearly grey-white luster under natural light. The best color is under MW, almost a lavender. Found in nepheline syenites, syenitic pegmatites - alkaline complex. Green fluorescence is likely uranyl activated salts. The feldspar is a nicely fluorescent magenta color, strong for the species.
The eudialyte is a beautiful, gemmy pink-red in daylight. Rare to find pieces with vlasovite and agrellite viewable together. They are, sadly, most often found on opposite surfaces.
Agrellite exhibits a brief intense phosphorescence (BIP) of yellowish color when quickly removed from under a shortwave (or midwave) UV light.
