Conflict diamonds, also known as blood diamonds, are rough diamonds used by rebel movements or their allies to finance armed conflict aimed at undermining legitimate governments.

Most people are unaware of the role diamonds play in bringing real benefits to people in the countries around the world where diamonds are sourced. Nowhere is this more evident than in Africa. It is also in Africa that this same resource has been used to fund conflict. In 2000, a coalition of governments, non-governmental organizations and the diamond industry worked together to address this issue. In 2002, they established the Kimberley Process Certification System, a UN-backed process that has virtually eliminated the trade in conflict diamonds. Today, over 99% of the world's supply of diamonds is from sources free of conflict.
