Tenebrescent Red Sodalite (Hackmanite)
Tunuliarfik, Ilimaussaq Complex, Greenland
2" x 2" x 1 1/4", 2.3 oz
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. This is probably the most dramatic example of tenebrescence in sodalite from anywhere. This process is easily reversed in seconds using a bright white light, and can be repeated over and over.
Longwave fluorescence is a bright orange/yellow and the shortwave fluorescence shifts to a beautiful rusty orange (caused by the intense tenebrescence).
These pieces are also nicely phosphorescent.
