The diamond is considered the most famous, elegant and valuable jewel in the world. It is the hardest substance found in nature. Its hardness and high dispersion of light make it useful for industrial applications and jewelry.
Diamonds were made as a result of great volcanic heat and pressure. A volcano is a mountain with a hole in the top. When a volcano is very active it sometimes explodes and causes great damage.
Diamonds were pushed towards the surface of the earth-millions of years ago-by a number of great volcanic explosions. It is in the narrow volcanic pipes that diamonds are found. They are also found among the sand and stones of certain riverbeds, and in a few places on the floor of the sea, for they were washed down the mountainsides by the rain.
Diamonds are very rare. There are not many diamond pipes or diamond-producing rivers in the world. During the last century, adventurers from Europe went to Brazil, because they had heard that there were diamonds in the River Amazon. [34]Most of these early diamond miners died of illness or were lost forever in the great forests.
The earliest known diamonds were found in India many centuries ago. The most recent and exciting discoveries have been made in Eastern Russia. But most of the world’s diamonds now come from the Congo, from Tanzania-which has the largest diamond mine in the world-and from South Africa.
