Color Characteristics & Optical Behavior

Water-clear doubly terminated crystals housing golden-yellow to amber droplets of ancient liquid petroleum that fluoresce bright electric blue-yellow under longwave UV light.

Geological Context & Pakistani / Global Localities

A celebrated Pakistani specialty from the sedimentary formations of Balochistan (Kharan/Chagai) and Khyber Pakhtunkhwa, where quartz crystallized in hydrocarbon-rich pockets millions of years ago.

Collector Interest & Rarity Factors

Highly sought after by inclusion specialists, gemologists, and fluorescent mineral collectors for its moving gas bubbles (enhydro/hydrocarbon) and dramatic UV fluorescence.

Fine Jewelry Applications

Set in protective cages, pendants, or collector rings without recutting the natural diamond-like doubly terminated habit.

Treatment Considerations & Disclosure

100% natural geological phenomenon; never heat, as expansion of trapped liquid hydrocarbons can fracture the crystal.

Care & Cleaning Instructions

CRITICAL: Keep away from heat sources, hot water, steam, and ultrasonic cleaners. Clean only with a cool damp cloth.

Traditional Meaning

Traditional Symbolism & Cultural Heritage

Celebrated as a geological time capsule preserving prehistoric organic fluids within crystal walls.

Note: Cultural and birthstone traditions are presented strictly as historical folklore, never as scientifically verified medical or metaphysical effects.
