I. The Metaphysical Reading
How the stone has been held.
Fuji lava stone is worked with as a stone of grounded release, often carried as a diffuser bead where a drop of essential oil is absorbed into its pores. Practitioners hold it as a stone that takes on what it is asked to carry — and as a reminder to periodically empty it out.

II. The Scientific Reading
What the lattice actually does.
Fuji lava stone is vesicular basalt erupted from Mount Fuji's stratovolcanic system, whose porous texture comes from gas bubbles trapped as the low-viscosity basaltic magma quenched at the surface. It is a plagioclase-pyroxene-olivine assemblage typical of subduction-zone basalts; the porosity is what makes it useful as an oil-holding bead but also relatively fragile compared with solid basalt.
