Quartz, Double Terminated, Petroleum Enhydro
An Enhydro/Enhydros is described as a natural water or fluid filled chamber that is found within a crystal or mineral. Scientists prefer to call the majority of them “fluid inclusions,” The crystals or minerals grow around the liquid deposits and trap it within forever, unless it is broken open by natural conditions or manipulation by man. These crystals were formed many millions of years ago.
Occasionally found in fluid inclusion chambers are dark brown to yellow petroleum oil. These oily liquids have been likened to "fossil fuel." Quartz crystals containing liquid yellow petroleum oil may be referred to as "Golden Enhydro" crystals.
A large majority of fluid inclusion chambers contain air bubbles. The gas bubbles which are found in enhydro/fluid chambers are usually composed of water vapor, methane, or carbon dioxide. An air bubble will always float upward when you move the crystal in various directions, unless it is trapped inside the chamber. Most chambers will hold only one air bubble, but there are some rare ones that are capable of having multiple air bubbles.
These quartz crystals containing petroleum oil fluoresce in a light bluish-white or yellowish-white color under longwave and shortwave ultraviolet light but seem to fluoresce more strongly under longwave. The entire fluid filled chamber will fluoresce when the fluid inclusion is yellow petroleum oil. This will usually cause the entire crystal to radiate the color of the fluorescence.
Only Individual crystals with water like clarity, only yellow to brown petroleum inclusions, and more than one methane bubble are graded AAA.
