This piece of gemmy sodalite is blindingly bright under all wavelengths, MW, SW and LW and deeply tenebrescent. It is the most interesting under midwave. There is an unknown deep blue mineral we haven’t seen before. There are also spots of violet which we think is leucophanite. This piece is also slightly phosphorescent.
The sodalite on this piece changes color when exposed to UV (SW), darkening to a grape purple (almost black) as shown in the GIF below - a unique hue compared to other Greenland sodalites. Under LW the bright orange fluorescence is unmistakable.
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.
