Crystallized Malachite Mineral

 

 

A great piece of malachite originating from the Kolwezi mine in Democratic Republic of Congo. This relatively large piece is covered in a layer of crystals that sparkle incessantly as soon as it catches the tiniest amount of light.

Malachite was one of the first ores of copper but it also contains hydrogen, carbon and oxygen. Some of the world's finest material comes from Africa and the smooth variety of malachite which features distinctive banding is what people tend to be more familiar with. It's a popular lapidary material but as well as being porous, it's also relatively soft grading just 3½ to 4 on Mohs scale of mineral hardness.

One of the oldest green pigments known to man, the colour of malachite is caused by the presence of copper but interestingly, this also makes it a hazardous mineral to work with. The copper in the dust that's released whilst working with malachite is toxic and must not be inhaled hence protective breathing equipment is worn whilst the stone is being mined. Those who work with malachite whether it be mining, cutting or polishing wear protective respiratory gear and keep the toxic dust to a minimum by ensuring it remains wet.
