Product Description
Cut from a double-terminated Quartz crystal from Belouchistan, Pakistan, this artfully faceted gem contains negative cavity inclusions which are filled with liquid petroleum, appearing a bright yellow in daylight.
Bubbles of Methane gas are visible within the liquid petroleum, which move through the cavities when the stone is rotated.
The petroleum exhibits a strong greenish-blue fluorescence under UV light, as shown in image 1.
Faceted examples of this astonishing gem variety are not often encountered. The nature of the inclusions make faceting perilous, the crystals tending to shatter during the cutting process, and at over 8 carats, this is a large gem of its type.
Image 5 (longwave UV light) is a magnified view of the inclusion scene.
