In this guide, we’ll explore everything you need to know about hackmanite, from its meaning and properties to its uses in jewelry and beyond.

What Is Hackmanite?
Hackmanite is a rare variety of sodalite, a mineral known for its rich blue hues. What sets hackmanite apart is its tenebrescence—a fancy term for its ability to change color when exposed to light.
- Discovered in: Greenland (1896)
- Named after: Finnish geologist Victor Hackman

Hackmanite’s magic lies in its reaction to UV light. When left in the dark, it may appear pale or even colorless. But expose it to sunlight or UV rays, and it transforms into vibrant shades of purple or pink. This phenomenon is reversible, making hackmanite a favorite among collectors.
