Hackmanite is a rare sodium-rich variety of sodalite. This superb combination specimen features a 1.8 cm tall, sharp, gemmy and lustrous, pink crystal stalwartly perched upright on a matrix of lustrous, tan winchite. Winchite is a rare amphibole group mineral and these crystals from this locality set the world standard for the species now. Smaller hackmanite crystals are nicely scattered on the winchite. The hackmanite has beautiful orange fluorescence and yellow phosphorescence.
