Product Description
Afghanistan White Hackmanite Crystal – Rare UV Reactive Mineral (34.5 Ct)
Offered here is a genuine white Hackmanite crystal sourced from Afghanistan, weighing approximately 34.5 carats with dimensions of 29 x 25 x 15 mm. This is a single natural specimen preserved in its raw form, showing a soft white to off-white tone with a semi-translucent appearance. The crystal structure reflects its natural cubic formation, with visible growth patterns and internal characteristics typical of authentic, earth-formed material.
When exposed to ultraviolet light, this Hackmanite transforms dramatically, emitting a vivid pink to purple fluorescence. In dark conditions, it may retain a subtle glow for a short period, demonstrating its phosphorescent behavior. These optical reactions make it a highly sought-after specimen among fluorescent mineral collectors and UV mineral enthusiasts.
- 100% natural and untreated Hackmanite crystal
- Large single piece – approximately 34.5 carats
- White to milky color with semi-transparent clarity
- Strong UV reactive fluorescence (pink/violet glow)
- Displays temporary afterglow in darkness
- Cubic crystal habit, silicate mineral group
- Origin: Afghanistan
- Rare collector-grade mineral specimen
Geological & Mineralogical Notes
This Hackmanite specimen is a well-defined cubic crystal habit, confirming its formation within the isometric crystal system typical of the sodalite group. The blocky geometry and sharp growth faces shows crystallization in an open cavity within an alkaline igneous environment, most likely associated with nepheline syenite intrusions.
The translucent to semi-opaque body shows natural internal zoning and micro-fractures formed during cooling and later tectonic uplift. Surface textures indicate minimal post-formation alteration, preserving its primary crystal structure.
The strong pink to orange fluorescence under UV light reflects sulfur-related activator centers within the aluminosilicate framework, while the brief afterglow (phosphorescence) points to lattice defects capable of trapping and releasing energy. Overall, the specimen represents a naturally formed silicate mineral crystallized under silica-poor, alkaline geological conditions.
Frequently Asked Questions
What makes this Hackmanite unique?
Its ability to glow under UV light and briefly continue glowing afterward makes it a distinctive and collectible mineral.
Has the crystal been treated or enhanced?
No treatments or artificial enhancements have been applied. It remains in its natural mined condition.
Is this suitable for display purposes?
Yes. Due to its size, fluorescence, and rarity, it is ideal for display, educational use, or advanced mineral collections.
