I. The Metaphysical Reading

How the stone has been held.

Cavansite is worked with as a stone of clear speech under pressure, particularly in disciplines where the language is technical and easily misheard. Practitioners keep it on the desk during writing and public interviews.

II. The Scientific Reading

What the lattice actually does.

Cavansite is a rare hydrous calcium vanadium silicate whose brilliant blue colour comes from vanadium in the four-valent state within its orthorhombic framework. It forms as radiating spherulites on stilbite and heulandite in cavities of the Deccan Trap basalts, principally at the Wagholi quarries near Pune, India, discovered in 1988 and still the world's main commercial source.
