HACKMANITE
A rare variety of sodalite distinguished by its tenebrescent nature—its ability to change colour when exposed to sunlight or UV light, then gradually return to its original state. Typically appearing in soft violet, lavender, or grey tones, Hackmanite develops within silica-poor igneous environments where chlorine-rich conditions influence its structure. This reversible colour shift, combined with its smooth finish when polished, makes it a highly intriguing material for collectors.
