Azurite
Azurite is a copper carbonate mineral, very similar and often found forming alongside malachite. It has a hardness of 3.5 to 4 and forms in massive, botryoidal and rarely long, prismatic crystal formations. The name Azurite is derived from its deep azure blue color, one of the rarest natural blues in nature! Azurite has recently been recognized to be the pigment used for blue colors in many Medieval paintings! It can be found in Bisbee AZ, Mexico, Congo, Namibia, Australia, Morocco, and many locations in Europe.
Azurite is said to be good for foresight, vision, intuition and intellect. It also helps with migraines and vertigo.
