Question

Chocolate diamonds are actually brown diamonds and compared to the well- known white diamond

they aren't much worth. Diamonds are produced in mines. The best known diamond mines are in

Australia, South Africa and Russia. The largest diamond mine was discovered in 1976 in the desert of

Australia near a little creek named Lake ArgJioyle. Diamonds are created under very extreme

conditions of pressure and high temperature. It is a general misunderstanding that there exist only

white colourless diamonds. Actually, diamonds exist in many different colours of all the diamond

mines in the world, almost 80% of all diamonds produced are brownish in colour. Because they were

found in such large quantities compared to the other coloured diamonds, they were considered as

low-valued diamonds, only good for the industrial sector. But, a famous man called Le Vian came with

a marketing campaign to increase the popularity of the chocolate diamond. Instead of calling it a

brown diamond, he gave it popular names like caramel, chocolate, cinnamon and cognac. Since his

marketing campaign, chocolate diamonds are becoming very popular.

The value of a diamond is based on its shape, brightness and colour. Because white diamonds are

rare, their value is based on the fact that there are not many white diamonds around. But if you look

at the shape and brightness, then the brightest diamond in this world known to men is a brown

diamond. Before the development of the Argyle Diamond Mine in Australia in 1986, most brown

diamonds were considered, worthless for jewellery; they were not even assessed on the diamond

colour scale, and were predominantly used for industrial purposes.

However, marketing strategies changed in the 1980s and brown diamonds have become popular

gems. The change was mostly due to the supply: the Argyle mine, with its 35 million carats (7,000 kg)

of diamonds per year, makes about one third of global production of natural diamonds; 80% of Argyle

diamonds are brown. The percentage of brown diamonds is lower in other mines, but it is almost

always a significant part of the total production. Consequently, scientific research on causes of brown

colour in diamond and ways to alter it has intensified.
