Fluorescent Hackmanite

A fascinating and rare specimen of Hackmanite — a variety of Sodalite renowned for its remarkable tenebrescence (reversible photochromism) and vivid fluorescence under UV light.

• Mineral: Hackmanite (Fluorescent)
• Weight: 45g

Hackmanite is one of the most scientifically intriguing minerals in the collector's world. In natural daylight it typically appears pale pink to white, but under shortwave UV light it glows a vivid orange-red or pink. Even more remarkably, it exhibits tenebrescence — it darkens when exposed to UV or sunlight and then fades back to its original colour in the dark. A truly interactive and conversation-starting specimen that never fails to impress.
