Description: Mass: 306 g MIM number: 2212 Double terminated quartz with multiple secondary terminations. This crystal contains an uncommon 4-phase inclusion consisting of a gas bubble trapped in the petroleum, the yellow petroleum itself, a darker brown organic material, and black carbon inclusions. The gas bubble formed as the petroleum contracted more than the quartz after cooling, thus pulling a vacuum within the fluid which vaporized the lighter cuts of the petroleum and created this bubble. This sample is highly fluorescent under both short and long wave UV. Photographer: FMI / James Elliot
