Malachite derives its name from Greek word malakos - soft. According to another theory the word malachite comes from Greek malhe, which means grass.

 

Malachite is a semi-precious stone and also a valuable copper ore, hydrous copper carbonate. It is responsible for the green color of tarnished copper and bronze. Because of its distinctive bright green color and its presence in the weathered zone of nearly all copper deposits, malachite serves as a prospecting guide for that metal. Malachite has been used as an ornamental stone and as a gemstone. 

 

Mining Malachite began as early as 4000 BC by ancient Egyptians. In the Middle ages, malachite was worn to protect from black magic and sorcery. In Ancient Greece amulets for children were made of malachite. 
In the New Stone Age came the discovery of the possibility of extracting certain metals from the ores in which they generally occur. Probably the first such material to be used was malachite, then already in use as a cosmetic and easily reduced to copper in a strong fire. It is impossible to be precise about the time and place of this discovery, but its consequences were tremendous. Namely it led to the search for other metallic ores, to the development of metallurgy.
