Petroleum Diamond Quartz Crystal Decor
 
 
An unusual, double-terminated crystal formation, known as Diamond Quartz or Herkimer Diamond (if mined in Herkimer County, NY), grows in a diamond-like geometrical shape with 18 crystal faces. Rare varieties of Diamond Quartz crystals have trace amounts of very pure hydrocarbon liquid and gas (petroleum) inclusions, which makes them glow (fluoresce) bright yellow when exposed to UV light. This is one of those rare Petroleum Diamond Quartz crystals!
