Hackmanite is a rare and fascinating gemstone, known for its unique ability to change color under different lighting conditions, a phenomenon called tenebrescence or reversible photochromism. It is a variety of the mineral sodalite and is prized for its mysterious and captivating properties.
Appearance
• Color: Typically exhibits a soft pink, violet, or lavender hue, but its color can deepen or shift to purple or grayish tones when exposed to ultraviolet (UV) light. The color reverts when moved back into normal light or darkness.
• Clarity: Generally translucent to opaque, with a smooth, waxy luster.
• Tenebrescence: This rare trait allows hackmanite to temporarily change color, setting it apart from most other gemstones.
Composition
• Hackmanite is a sulfur-rich variety of sodalite, with the chemical formula Na8(Al6Si6O24)Cl2.
• It has a hardness of 5.5 to 6 on the Mohs scale, making it less durable compared to harder gems.
Sources
• Found in a few key locations, including Myanmar (Burma), **Afghanistan
