We've made contact with a miner in the Afghan areas and have a supply of mine fresh material. The fluorescent activators have not been studied very much from this area. It's very unclear what is going on with most of the material from this locality, but as we get more material and discover new fluorescent minerals we will have them analyzed for proper IDs. 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 - first picture), although it is very respectable under shortwave alone (second pic) - or even midwave UV or longwave UV alone.

 Under shortwave the calcite fluoresces a dark red-orange, and the diopside crystals fluoresce a bluish white. Under midwave UV (only) there are areas of a strong blue fluorescence from an unknown mineral - this is one of the few examples of midwave only fluorescence we have observed (several closeups of this area are shown at the bottom). Phlogopite is bright yellow under shortwave, shifting to a bright butterscotch color midwave and even deeper longwave (very few phlogopites have this multi-wave response). Midwave causes the calcite to pop very nicely. Longwave brings out the yellow color of the blue afghanite crystals. Midwave and longwave UV bring out the bright yellow of the marialite very nicely. If we were to display it under only one light, we would probably pick shortwave, preferably with a  midwave “kicker”.

Fluorescent Green Agate from Scott's Gulf, Smryna, Tennessee

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.

"Red" Sodalite (Hackmanite) - Deeply Tenebrescent Greenland Mineral

Red sodalite is named for the color it takes on when exposed to sunlight; it is nicely tenebrescent under longwave UV. Under shortwave UV the color deepens, in seconds, to almost black in some areas.
