Azurite

Azurite is a soft, deep blue copper mineral produced by weathering of copper ore deposits. 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. The blue of azurite is exceptionally deep and clear, and for that reason the mineral has tended to be associated since antiquity with the deep blue color of low-humidity desert and winter skies. The modern English name of the mineral reflects this association, since both azurite and azure are derived via Arabic from the Persian lazhward (لاژورد), an area known for its deposits of another deep blue stone, lapis lazuli ("stone of azure").

Azurite is soothing and calming for the emotions. It enhances psychic abilities and is very good to use for general healing.  It can be used to balance the electrochemical system of the body and provide a flow of energy from the 3rd eye to the heart chakra.
