Rich Fluorescent Purple Hackmanite Specimen lot Specimen - 142 g - (1)

Hackmanite is a rare variety of sodalite mineral celebrated for its unique fluorescence and tenebrescence — the ability to change color under different lighting conditions. This specimen displays a rich fluorescent purple hue, which becomes notably vibrant under ultraviolet light. Hackmanite typically forms in alkaline igneous rocks and is considered a collector's gemstone due to both its rarity and its fascinating optical properties. The purple fluorescent glow is caused by sulfur defects within the crystal structure, making it a favorite among mineral enthusiasts and collectors who appreciate its striking color shifts and luminescent qualities.
