The stone heats up fast in my hand and holds that warmth through the whole session, and the weight feels steady rather than heavy. I didn't expect to feel this settled and focused afterward, but the grounding really stuck with me for hours.

The grounding effect is real, I felt a noticeable sense of calm during my first session with the smooth obsidian. It's a bit heavier than I expected, so I have to hold it carefully, but the weight adds to the connection. Four stars because the surface could be more polished for comfort.
