I. The Metaphysical Reading
How the stone has been held.
Clevelandite is worked with as a stone of shelter and companionship, kept nearby during collaborative projects, communal living and the quiet work of holding space for other people's crystallisations. Practitioners hold it as a reminder that the ground stone can also be beautiful.

II. The Scientific Reading
What the lattice actually does.
Clevelandite is a bladed lamellar variety of the sodium feldspar albite that forms in the late, low-temperature stages of granite pegmatite crystallisation. Its intergrown blades often line miarolitic cavities and provide the matrix for tourmaline, beryl, spodumene and lepidolite specimens.
