Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits. Bornite is also found as disseminations in mafic igneous rocks, in contact metamorphic skarn deposits, in pegmatites and in sedimentary cupriferous shales. It is important as an ore for its copper content of about 63 percent by mass.
Peacock Ore (Bornite) is a crystaline variety of Chalcopyrite and they have very similar properties. Bornite is the name of the natural, untreated stone, while Peacock Ore usually describes its heat-enhanced state. Bornite has naturally occuring rainbow colours, but they are rare in nature. It is useful in providing protection from outside negativity; it also helps you to recognise the source of the negativity. It is a colourful stone for helping to dismiss grey days by inspiring hope and lifting your mood. As with the bird it is named after, its display is an inspiration and reminder that life is not limited to a mundane combination of atoms, but permeated by a magic that does not cease to exist because we cannot always perceive it! Bornite is an excellent healing stone. It can be used to assist in the building and re-building of your physical body. It renews perfection to cellular growth, composition and arrangement. It performs a major role in the amelioration of the origin, nature and course of disease, and it is quite useful in the treatment of imbalances in cellular metabolism and in alterations of tissue formations within your body.
