Diamond
Everyone knows how beautiful diamonds can be. But do you
know that a diamond is the hardest substance found in nature? Dia-
monds are crystals made of carbon. Scientists believe that diamonds
were formed long ago when parts of the Earth were under great
pressure and heat. Diamonds are so hard that they are used to cut
many other hard materials. But a diamond can only be cut by an-
other diamond, or by a man-made material called borazon. Dia-
monds are found in just a few places in the world. Miners must dig
into the earth to remove the diamonds. Sometimes tons of earth
must be removed and crushed to find just one small diamond. Some
of the diamonds are used in industry to cut hard materials. Other di-
amonds are polished and cut to become jewels. There have been
many famous diamonds in history. The largest, found in 1905,
weighed one and one'third pounds!
