A natural petroleum quartz crystal lot from Pakistan, 96ct total (50 pieces), ranging 8–15mm per crystal. Each piece contains natural petroleum fluid inclusions and exhibits vivid cyan-blue fluorescence under 365nm UV light — a dramatic optical property characteristic of this material.
Petroleum quartz from the Balochistan region of Pakistan is among the world's most unusual collector minerals: sealed liquid hydrocarbon inclusions fluoresce brilliantly under long-wave UV. A wholesale lot of 50 crystals — ideal for resellers, market stalls, UV display collections, crystal subscription boxes, or educational specimen sets. Crystals vary individually in size, shape, and fluorescence intensity. Price is for the complete lot.

About petroleum quartz
Petroleum quartz holds tiny pockets of natural oil, sometimes with a gas bubble, trapped while the crystal grew. It is 7 on the Mohs scale, but the inclusions make it sensitive to heat.
Cleaning
Rinse it in cool or lukewarm water, never hot, and let it dry away from heat. Skip ultrasonic and steam cleaners: warmth and vibration put pressure on the oil and gas inclusions.
Wear and storage
Quartz crystals are hard, but their points and edges can chip if knocked. Store the cluster padded and apart from other specimens.
