Malachite is a carbonate hydroxide mineral and its green banded colour is due to the copper content. Individual crystals are rare as it forms mostly in botryoidal , fibrous, or stalagmitic masses. Malachite is very often carved into ornaments or statues. Only use malachite in its polished form as the high copper content makes it toxic. Malachite absorbs negative energy and pollutants from the environment and body. It can guard against radiation and electromagnetic pollution.
