Sodalite exhibiting a slight tenebrescence, bright orange LW, slightly dimmer SW. Under white light areas of the sodalite have a bluish hue, we're not sure of the reason. These areas are less fluorescent, possibly an unidentified mineral that is a homogenous blend with sodalite. All sits on a bed of lujavrite.
The area these pieces were found is also unusual - a spot in the middle of the Taseq Slope, no other major deposits found in the area.
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.
