Greenland sodalite with interesting patterning. The LW fluorescence is knock-your-socks-off bright. Green areas are likely natrolite green. There is some magenta fluorescing feldspar.
This material is slightly tenebrescent. Upon exposure to SW UV the sodalite on this piece changes color to a light purple - in seconds! Expose it to a bright white light (UV free halogen or LED spotlight held directly on the rock) and it reverts back to its natural color almost immediately.
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.
