I. The Metaphysical Reading

How the stone has been held.

Chrysocolla is worked with as a stone of truthful speech, kept nearby during difficult conversations, teaching and community work. Practitioners hold it as a reminder that a clear voice is a form of tenderness, not a form of force.

II. The Scientific Reading

What the lattice actually does.

Chrysocolla is a hydrated copper silicate that forms in the oxidised zones of copper deposits, often intergrown with malachite, azurite and quartz. Pure chrysocolla is soft and porous; the gem material sold as 'gem silica' is chrysocolla naturally impregnated with chalcedony, which raises its hardness to around 7.
