I. The Metaphysical Reading
How the stone has been held.
Brochantite is worked with as a stone of restorative growth in places long worked by human hands. Practitioners keep it nearby when tending a garden, a business or a relationship that has been overused and is being brought back into balance.

II. The Scientific Reading
What the lattice actually does.
Brochantite is a hydrous copper sulphate that forms as a secondary mineral in the oxidised zones of copper deposits, particularly in arid climates where sulphate solutions are stable. It occurs as brilliant green acicular crystals in radiating sprays, most famously at the Chuquicamata and Collahuasi mines in the Atacama Desert of Chile, at Tsumeb in Namibia and at Bisbee in Arizona.
