I. The Metaphysical Reading

How the stone has been held.

Geyserite is worked with as a stone of rhythmic release, carried by practitioners who work in cycles of build and vent. It is held to help the body honour a schedule of expression rather than storing pressure indefinitely.

II. The Scientific Reading

What the lattice actually does.

Geyserite is a variety of siliceous sinter — amorphous opal-A precipitated from silica-supersaturated hot-spring and geyser water as it cools at the surface. Each eruption or splash deposits a thin silica film, and successive layers build up the characteristic laminated, botryoidal and sometimes pisolitic aprons around geyser vents. It is also one of the oldest recognised habitats for microbial life on Earth.
