OMG HISTORY OF DIAMOND

THE HISTORY OF DIAMOND MINING AND DIAMONDS IN SOUTH AFRICA TO INDIA

Let's coming to the point friends.

 The 1867 discovery of diamonds in the Cape Colony, South Africa, radically modified not only the world’s supply of diamonds but also the conception of them. As annual world diamond production increased more than tenfold in the following 10 years, a once extremely rare material became accessible to Western society with its growing wealth. Today South Africa maintains its position as a major diamond producer.Working resumed in 1945, but its fourth life really began in 1979 with the opening up of the mine below the Gabbroe sill, a 70-meter geologic intrusion of barren rock which cuts right through the pipe some 400 meters below the surface. Production from this new source has not only given the mine its longest life, but one that should enable production to continue for another fifteen years.

In the early years of its existence, the Premier Mine produced many large diamonds, including, of course the Cullinan in 1905, and since working was restarted in 1945 the mine has continued to yield some exceptional stones

       WHAT ABOU TO INDIA INVOLVED                        HISTORY OF DIAMOND

   

Until the 18th century, India was thought to be the only source of diamonds. When the Indian diamond mines were depleted, the quest for alternate sources began. Although a small deposit was found in Brazil in 1725, the supply was not enough to meet world demands.medical aid and were thought to cure illness and heal wounds when ingestedSurprisingly, diamonds share some common characteristics with coal. Both

arecomposed of the most common substance on earth: carbon.

What makes diamonds different from coal is the way the carbon atoms are arranged and how the carbon is formed. Diamonds are created when carbon is subjected to the extremely high pressures and temperatures found at the earth’s lithosphere, which lies approximately 90-240 miles below the earth’s surface. 

        Why are diamonds expensive ?

Diamonds are very expensive because they occur at relative few places in the world.like

Russia and south Africa and are very difficultto extract.They are made of carbon and are the hardest substance known to us, wich is the result of the high pressure at their place of origin deep below the Earth's surface. They are naturally thrown up on the Earth's surface through volcanic eruptions. Being very hard they are mined in the vents of the extinct volcanoes. Being very hard omg they have great industrial use for grinding tools.
