Which countries do diamonds come from?

Diamonds were first discovered in India hundreds of years
ago, but there are now more t
han twenty countries that
produce and sell diamonds. 
Today, more diamonds are
mined in Australia than any other country in the world. 
Most of these diamonds are found in the Kimberley area.

How are diamonds made?
Diamonds are crystals whic
h are formed deep inside the
earth.  This happens more than
150 kilometres below the
ground.  Here, it is very
hot indeed and rocks are being
very strongly squeezed from above.

When the diamond crystals are
found, they look quite dull
and smooth.
