Hackmanite (UV Reactive) – Afghanistan – 200 grams

Hackmanite (UV Reactive) – Afghanistan – 200 grams

Item Description:
This 200 gram lot of natural Hackmanite comes from the Sar-e-Sang locality in Afghanistan, a region known for producing some of the most interesting tenebrescent material in the world. 

Hackmanite is famous for its color-change reaction when exposed to UV light. In normal daylight, the stones appear grayish-white to pale lavender. Under longwave UV, they shift dramatically into pink, purple, or violet tones. When the UV source is removed, the color slowly fades back to its original state.

Each piece is natural and unpolished, showing authentic crystal texture and surface character. Photos are taken in different lighting conditions to show the natural variation and UV response. No photo editing or artificial enhancement is used. Pieces are shown in hand for scale. You will receive a similar quality and mix, not necessarily the exact stones pictured.
