Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth).
Blood Diamonds, also known as Conflict Diamonds are stones that are produced in areas controlled by rebel forces that are opposed to internationally recognized governments. The rebels sell these diamonds, and the money is used to purchase arms or to fund their military actions. Blood Diamonds are often produced through the forced labor of men, women and children. They are also stolen during shipment or seized by attacking the mining operations of legitimate producers.
