I. The Metaphysical Reading
How the stone has been held.
Garnet in wollastonite is worked with as a stone of bridged temperaments, useful when a warm impulse has to speak with a cool structure. Practitioners hold that the pale wollastonite translates and the garnet supplies the heat.

II. The Scientific Reading
What the lattice actually does.
Garnet in wollastonite is a classic calc-silicate skarn: limestone or dolomite baked and chemically altered where a granitic intrusion came into contact with it. Calcium liberated from the carbonate combines with silica from the intrusion to grow wollastonite fibres and grossular garnet crystals side by side. The assemblage records a specific pressure-temperature-fluid regime at the contact zone.
