What are conflict diamonds?
In 1998, Global Witness, a non-governmental organisation (NGO), made the world aware that certain rebel movements in Africa were selling, amongst other things, illegally obtained diamonds, known as conflict diamonds, to fund their wars against legitimate and internationally recognised governments.
Gillett’s has a policy of zero-tolerance towards conflict diamonds. Measures such as the Kimberley Process, which tracks diamonds from mine to market, makes it possible for the industry in partnership with the United Nations, governments, and non-governmental organizations to police diamond exports to prevent the trade of illegal diamonds.
Today, over 99% of the world's supply of diamonds is from sources free of conflict as a result of these measures.
Diamonds are mined throughout the world, including major mines in Australia, Russia, Africa and Canada. Diamonds are a major source of economic support in African countries, which employs and enables the provision of health care to thousands. For more information on this issue, see DiamondFacts.org.
