What is Enhydro (Quartz)?
Enhydro (Quartz) is usually a cloudy-white chalcedony or agate geode that has drops of fluid captured inside its cavities. This unusual characteristic gave the material its name — enhydros means containing water. These inclusions form interesting bubbles, which can sometimes move about, and attractive surface patterns that make them a prized stone.
