Hackmanite is a rare variety of sodalite known for its tenebrescence—an optical effect where the stone changes color under UV light. These Burmese stones appear soft lavender to gray in daylight but shift to vivid purplish tones under shortwave UV, then gradually return to their original state.
This reversible color change is caused by trace sulfur in the crystal structure and is characteristic of quality Hackmanite from Myanmar, which is especially valued for its clarity and response to UV
