This specimen weighs 69 Gram and features a striking combination of Hackmanite and Sodalite crystals from Afghanistan. The piece displays exceptional fluorescence, phosphorescence, and tenebrescence, glowing vividly under UV light and even holding a temporary afterglow once the light source is removed. Its multiple luminescent properties make it an extraordinary mineral specimen.

Hackmanite, a sulfur-rich variety of sodalite (Na₈(Al₆Si₆O₂₄)Cl₂ with sulfur inclusions), is famous for its tenebrescence, the ability to change color when exposed to sunlight or UV radiation. Sodalite (Na₈Al₆Si₆O₂₄Cl₂) complements it with additional fluorescent effects. These minerals are also found in Greenland, Canada, and Russia, but Afghan material is especially prized for its intense UV reactions and rare phosphorescent glow.

This phosphorescent Hackmanite–Sodalite combination is highly valued by collectors of fluorescent minerals. Its interplay of rare optical effects, vibrant glowing colors, and natural crystal formation make it an impressive addition to any serious mineral collection or display.
