Hackmanite is a variety of sodalite with the chemical formula Na₈(Al₆Si₆O₂₄)Cl₂, exhibiting tenebrescence, where its color deepens when exposed to sunlight or UV light and then fades in darkness. While Afghanistan produces some of the finest hackmanite, this mineral is also found in Canada, Myanmar, Greenland, and Tanzania. Its unique interplay of light and color makes it one of the most fascinating fluorescent minerals.

With its impressive size, strong phosphorescence, and rare tenebrescent effect, this specimen is a standout addition for collectors and display enthusiasts. Its optical properties make it highly desirable and visually captivating under varying light conditions.
