[b]Diamond[/b] is pure form of carbon in its most concentrated form. [b]Diamonds[/b] are generally excavated from deep in the earth. The [b]diamonds[/b] are formed 100 miles below the earth surface by very high heat and pressure which transforms carbon into diamonds. For the formation of diamonds the carbon should be exposed to a heat of 400 degrees celcius and a pressure of 30 kilobars.
