Rich Fluorescent Purple Hackmanite Specimen from Badakhshan Afghanistan Specimen - Height: 40 mm - Width: 90 mm - 185 g - (1)

Hackmanite is a rare and fascinating variety of sodalite known for its distinctive ability to exhibit tenebrescence—a reversible change in color when exposed to sunlight or UV light. The rich fluorescent purple hackmanite specimen from Badakhshan, Afghanistan, is prized among mineral collectors for its vibrant color and unique optical properties. Found in evaporite deposits and alkaline igneous rocks, hackmanite typically forms granular or crystalline masses and is notable for its interaction with light, making it a compelling subject for study and display. The purple fluorescence exhibited increases its desirability among collectors and adds visual intrigue beyond the usual blue or gray hues of sodalite group minerals. Such specimens demonstrate the complex chemistry and structural peculiarities that contribute to hackmanite's unusual characteristics.
