A deeply tenebrescent piece of hackmanite (sodalite) with bright blue analcime, minor tugtupite, minor polylithionite and some weird unknowns. Under midwave UV, you can see an area of pink – an unknown mineral. Under white light, you can see pink eudialye throughout the specimen.
The animation shows the color change (tenebrescence) after exposure to longwave and shortwave UV.
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.
