The etymology of the name “malachite” comes from the ancient Greek “malakhē” (μαλάχη), meaning “purple”, in reference to the green color of the leaves of the common mallow plant (Malva sylvestris). The resemblance between the green hue of this plant and that of the mineral inspired the name.
Other interpretations suggest that the word “malachite” may also derive from “malakos” (μαλακός), which means “soft” or “tender” in Greek.
