FLUORESCING SODALITE SPECIMEN
Ilímaussaq Complex, Tunuliarfik, Greenland
The Ilímaussaq complex is an unusual mid-Proterozoic igneous intrusion located at the southwestern tip of Greenland, famous for its fine fluorescing mineral specimens. Unlike many other such minerals, this sodalite specimen is in fact rather an attractive rock even under normal lighting conditions. The grey surface is speckled with white and one face covered in crystals of a lovely soft green color. Bath it in the invisible rays of long wave light, however, and it springs dramatically to life as the green crystals glow with a fiery orange color. This form of the mineral is known as hackmanite sodalite and also exhibits tenebrescence, the ability to change color in sunlight, a characteristic exploited in the manufacture of photo-sensitive sunglasses. This good-sized specimen measures 7¼ x 5½ x 5½ inches.
