This piece of very gemmy sodalite is blindingly bright under all wavelengths, midwave, shortwave and longwave. 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.

The tenebrescence is almost 100% on the front side of the specimen.

Tenebrescence of Greenland fluorescent sodalite is amazing. This is a piece of a deeply tenebrescent sodalite. Note how when the shortwave light is first turned on, the sodalite fluoresces a bright orange but almost immediately shifts to a burnt orange as the tenebrescence sets in.

Willemite, Calcite, Fluorite from the Garpenberg Mine in Sweden

The Garpenberg mine is located in Bergslagen, a very old mining area in the southern part of Sweden.

The mine is very active today and is one of Europe's most progressive underground mining operations. Collecting is not possible, and the few specimens that reach collector's hands are highly prized. The mineralogy is quite similar to that of Franklin NJ.
