with crystal shaped liquid inclusion and a gas bubble. Field of view ca. 1.2 mm.
The liquid is typically saline water and the gas is carbon dioxide. But I am not aware of any scientific research for the inclusions from Osilo. If this crystals are put in a freezer, the water is freezing which causes cracks in the crystal and destroys crystal and bubble. In thin sections the freezing point can be used to determine the salinity of the water inclusion.
