Hackmanite is a rare sulfur chloric sodium aluminum silicate member of the Sodalite family. This is one of the very few minerals that will change colour when exposed to light as well as UV reflective. It can be seen in a variety of colours such as grey, green, yellow, violet, pink, and blue, but most commonly found in a dusty white. Hackmanite was first discovered in Greenland. It was named after the Finnish Geologist Victor Axel Hackman.
Hackmanite helps grant ones access to their crown chakra while enhancing their mental capabilities. One will be able to see the strength that the human mind possesses, which can lead them to the gateway of higher knowledge.
