Hackmanite 8mm Round - 15-16 Inch Golden but also for industrial purposesDiscovered in Greenland in the late 1890's, hackmanite is named for Finnish geologist Victor Hackman. It is a rare occurrence to find gem grade hackmanite; at best, most crystals are translucent. Hackmanite is the light pink to pale violet variety of sodalite. It is a particularly unusual gem because it exhibits a special optical property known as tenebrescence, a type of reversible photochromism. Hackmanite is very reactive under UV light.
