Diamonds

Trend Watch
Today, diamonds are mined in over 25 countries around the world. Europe and New York are known as the centre of diamond wholesaling. Although most diamonds are of the traditional, clear type and diamonds of every color are found naturally. Colored diamonds are the same structurally as normal diamonds, but include trace amounts of other minerals, which give them their individual cover.

Diamonds are formed when carbon-bearing materials are prolonged to intense pressure and temperatures. This occurs under the earth's continental crust, where temperature is around 2,200 degrees Fahrenheit. Diamonds are mostly mined in Africa, but there are sufficient deposits in Australia, South America, Russia, and Canada.

Diamond color is graded from D-F (colorless) through G-J (near colorless), K-M (faint yellow), N-R (very light yellow) down to S-Z (light yellow). In the K-R range, you sometimes get very light brown called "champagne" and a darker brown called "cognac", these both are very attractive.
