Top grade & rare fluorescent oil captured in quartz crystal.
The petroleum oil is the yellow or brown fluid trapped in the crystal forever. The liquid is moving within the trapped chamber.
In addition to the petroleum there is also solid carbon and gas bubbles trapped in some of the inclusions - creating 3 phase inclusions which are very rare and prized in specimen collections.
The crystal glows very strongly under UV light due to the inclusions. A must have for any specimen collection.
