Gemology: fluid inclusions (enhydro) with moving bubbles in quartz!

Описание: Hey guys! My name is Egor Gavrilenko. I'm a PhD in Geology, a gemologist, and a gem cutter.

In this video, I’m showing a colorless quartz cabochon that I cut from a quartz crystal from China, specifically to highlight its unique inclusions. These are multi-phase inclusions: at room temperature, they contain a liquid phase (essentially water), a gaseous phase in the form of a vapor bubble, and a solid phase of black hydrocarbon particles. These solid particles are slightly denser than water, which causes them to settle at the bottom of the cavity. However, some fine particles cling to the surface of the bubble, giving it a black appearance.

When we flip the stone, gravity causes the solid particles to fall to the bottom again, while the bubble tends to rise within the cavity. The space is very limited, when the particles accumulate on top of the bubble, I gently shake the stone so they fall away and the bubble can continue to rise. On the left side, you can also spot another, smaller black bubble that moves up and down as the stone is rotated.

Hope you enjoy this video. If you're interested in gem inclusions, I have a dedicated website on the topic, check it here: https://www.gems-inclusions.com/
