Petroleum quartz crystal 29.8ct fluorescent

A natural petroleum quartz crystal from Pakistan, 29.8ct measuring 22×22×15mm. This large single crystal contains natural petroleum fluid inclusions and exhibits vivid cyan-blue fluorescence under 365nm UV light — a dramatic and scientifically fascinating optical property unique to this material.

Petroleum quartz from the Balochistan region of Pakistan is among the world's most unusual collector minerals: the sealed liquid hydrocarbon inclusions fluoresce brilliantly under long-wave UV, transforming the crystal into a glowing teal lantern. A must-have for mineral collectors and UV enthusiasts. The primary product photo shows the stone under UV illumination.
