Malachite is a green-copper carbonate. It displays a typical botryodal habit, which resembles a bunch of grapes. When cut through and polished, it shows a series of attractive light and dark green concentric growth rings that run parallel to the outside of the surface.
Malachite is a power stone for intense inner transformation and soul catharsis.
Medieval lapidaries used malachite for curing cramps, seizures and for easing childbirth.
