A very large piece of virtually solid fluorescent sodalite, quite gemmy. Under MW you can see an unknown white fluorescent mineral, we've never seen this before. Interesting piece. It is phosphorescent which is very unusual for sodalite. Greenland sodalite comes in all colors. This piece is a very bright piece under both SW and LW.
This material is slightly tenebrescent as shown in the animation/GIF below. The LW fluorescence is knock-your-socks-off bright.
