Tenebrescent yellow sodalite from Greenland

Shown here is a very modest sized but lovely specimen of tenebrescent yellow sodalite, from Taseq Slope East, Ilímaussaq complex, Narsaq, Kujalleq, Greenland.

In the first picture, it is shown fluorescing under shortwave UV; then in the next pictures, the very bright orange longwave UV response, the tenebrescence and the natural color of the sodalite after "bleaching" the tenebrescence with a bright white LED light are shown. Then the opposite side of the specimen is shown in the same order in the next pictures.
