The fluorescent activators have not been studied from this area and itÕs very unclear what is going on with most of the material from this locality. But they sure do make for some confusing but amazingly beautiful fluorescent specimens.
This piece (as most from Afghanistan) is best displayed using multiple wavelengths, and shows best under a combination of longwave, midwave and shortwave (fullwave), although it is very respectable under SW alone (second pic) - or even MW or LW alone.
There are many scapolite (var. marialite) crystals that are fluorescent a bright yellow LW and dimmer yellow SW. The phlogopite glows a bright yellow SW and a butterscotch color MW (and LW).
Tricolor phlogopite such as this is unusual.
First, an animation showing the difference between the UV flashlight we recommend (365nm filtered UV flashlight) versus unfiltered 395nm UV flashlights we see many folks carrying around at shows. So. much. visible purple light. We selected a bunch of rocks as a demonstration. Took pictures of them under his flashlight without the filter and then with the filter.
A major component of rock collecting (for us) is simply getting out in nature. A buddy dragged us out to a very remote area here in middle Tennessee to hunt for fluorescent green agate. Since we consider ourselves pure "Glow Hounds" we weren't anticipating any glow rocks, just the beauty of the area, but we brought our UV lights anyway.
