On the second side of the sphere, under midwave UV, you can clearly see the bright, violet leucophanite crystals. Leucophanite is rare. It's only found in a few places around the world - most notably Norway, Canada MSH), and Greenland. This is probably one of the only spheres containing clear leucophanite crystals in the entire world.
A nicely tenebrescent and fluorescent sodalite sphere containing a very interesting mix of mineralogy. The green areas are likely chkalovite, blue is likely analcime. If you look closely, you can see some minor tugtupite veining as well as minor dots of silver polylithionite.
Under shortwave UV, you’ll notice the sodalite darkening to a reddish-orange due to the tenebrescence that is occurring.
"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.
