THE NATURAL DIAMOND

were found behind the River Krishna. This is followed by ancient Rome, China, South America and, since 1867, the first diamonds in South Africa; the latter, become an important centre of diamond mining, replaced India at world level, which by then had exhausted its own mining centres. A diamond is composed of billions of carbon atoms, each of which is strongly connected with another four, which makes it the hardest natural existing substance. The formation of diamonds, shaped by natural explosive forces, occurs due to an extraordinary phenomenon: at a depth of more than 120 km, through intense heat between 900°C and 1300°C, at a pressures of 45 kbar, over millions of years, the carbon crystallizes to form diamonds. Subsequently, to embark on their journey to the earth’s surface, the diamonds free themselves from the intense pressure and heat under which they are formed, when part of the earth’s mantle melts into magma, which then erupts quickly on the surface, carrying the diamonds with it.
