Azurite is named after its rich blue colour. It was formerly known as Chessylite, after the mine in Lyon, France, that is now depleted. Azurite occurs in and near copper deposits alongside malachite. The distinct blue colour of Azurite was used as a pigment, but it has also been used in ornamental objects. Azurite is now sourced from Australia, Chile, Mexico, Russia and the USA.
