Azurite is a soft, deep-blue copper mineral produced by weathering of copper ore deposits. During the early 19th century, it was also known as chessylite, after the type locality at Chessy-les-Mines near Lyon, France. The mineral, a carbonate with the chemical formula Cu3(CO3)2(OH)2, has been known since ancient times, and was mentioned in Pliny the Elder’s Natural History under the Greek name kuanos (κυανός: “deep blue”, root of English cyan) and the Latin name caeruleum. Since antiquity, azurite’s exceptionally deep and clear blue has been associated with low-humidity desert and winter skies.
Malachite is a copper carbonate hydroxide mineral, with the formula Cu2CO3(OH)2. This opaque, green banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and spaces, deep underground, where the water table and hydrothermal fluids provide the means for chemical precipitation. Malachite was used as a mineral pigment in green paints from antiquity until about 1800. Malachite often results from the weathering of copper ores, and is often found together with azurite (Cu3(CO3)2(OH)2), goethite, and calcite. Except for its vibrant green color, the properties of malachite are similar to those of azurite and aggregates of the two minerals occur frequently. Malachite is more common than azurite and is typically associated with copper deposits around limestones, the source of the carbonate.
Malachite is a stone of balance, abundance, manifestation and intention. Malachite absorbs energy and draws emotions to the surface. It clears and activates all Chakras, and is especially helpful in the stimulation of the Heart and Throat Chakras. An extremely powerful metaphysical stone, Malachite is often called the “stone of transformation” and is used for deep energy cleaning, bringing healing and positive transformation to the wearer.
