Nations who agree to participate in the Kimberley process are not permitted to trade with nonmember Nations. The Kimberley Process is believed to have significantly reduced the number of Conflict Diamonds that are reaching international gem markets. Today 81 governments and several non-government organizations abide by the Kimberley Process. The only two nations which remain under Kimberley Process sanctions as of December, 2006 were Liberia and Ivory Coast. The World Diamond Council estimates that 99% of all diamonds are now conflict-free.
