About Hackmanite
Hackmanite is a rare and captivating variety of sodalite, a sodium aluminium silicate mineral known for its striking colour-changing ability called tenebrescence. This unique property allows Hackmanite to change colour when exposed to sunlight or ultraviolet light, shifting from soft violet or pinkish hues to pale grey or even colourless, then returning to its original colour in darkness.
Named after the Finnish geologist Pekka Hackman, this mineral is chiefly found in Greenland, Afghanistan, Myanmar, Canada, and the USA (notably in Arkansas). Hackmanite forms in crystalline or granular masses with a Mohs hardness of around 5 to 6, making it moderately soft but prized for its metaphysical uniqueness rather than durability.
