What Is Hackmanite?

Hackmanite is a rare variety of sodalite rich in sulfur centers that respond dramatically to radiation and light. Its UV glow and reversible color change (tenebrescence) make it one of the most interactive minerals a collector can own. It’s often found in only a handful of global localities, and strong-glowing pieces like this are prized for both display and scientific interest.
