          Orange hackmanite is a variety of the mineral sodalite, which belongs to the feldspathoid group of minerals. Hackmanite is notable for its ability to exhibit tenebrescence, a form of reversible color change that occurs when exposed to UV light or after being exposed to sunlight. When in its natural state, orange hackmanite typically appears a pale yellow or colorless, but it can turn bright orange or pink under UV light, and it may return to its original color when the UV light is removed. This unique characteristic makes it a sought-after specimen for collectors and enthusiasts. Hackmanite, including the orange variety, is often cut into gemstones and used in jewelry, though its color-changing properties add a level of intrigue to its appeal. The mineral was first discovered in the 19th century and is named after the Finnish chemist Victor Hackman. In terms of its composition, orange hackmanite contains sodium, aluminum, silicate, and chloride, and it often forms in granular or massive crystals.
