STEENSTRUPINE with fluorescing SODALITE - Taseq, Ilimaussaq, Greenland
Orange LW and SW fluorescent Sodalite with lots of dark brown Steenstrupine-(Ce), tiny dark green Aegirine needles, and some green SW uranyl-activated fluorescence.
Steenstrupine is a very rare mineral found in only 4 regions worldwide.
Some areas of Sodalite are tenebrescent - areas assume a pink coloration upon irradiation with SW UV, the color will fade on exposure to light.

To show the fluorescent response the specimen was illuminated using 6 watt 254nm (Short Wave) / 366nm (Long Wave) UVGL-58 lamp (you need a proper UV light source to observe the fluorescence, more powerful lamp = brighter response).
