About hackmanite
Hackmanite is a sulfur-rich variety of sodalite notable for its tenebrescence (reversible photochromism): its color can deepen or change when exposed to ultraviolet light and then gradually fade in the dark or under different lighting. It typically appears light violet, pinkish or grayish, with Mohs hardness around 5.5–6 and fair toughness. It is usually used as a cabochon or bead rather than a heavily worn faceted gem.
