Quartz Crystal with Petroleum Inclusions - Pakistan
Contributed by: Chris Clemens
Date: Apr 29th, 2026
Locality: Balochistan, Pakistan (See on Mindat)
Size: 26 mm
Description:
This single, double terminated Herkimer diamond-like, quartz crystals is from Pakistan. It is a beautiful little specimen when viewed under natural lighting but explodes with bright blue/white fluorescence under UV due to numerous internal petroleum (oil) inclusions that glow brightly under UV. The fluorescence is similar under all UV wavelengths but is a little warmer under longwave. The length of the crystal is 26 mm.
