dont buy the "blood diamond" somewhere from africa...

  diamonds - small pieces of carbon with no great intrinsic value - have been the cause of widespread death, destruction and misery for almost a decade in the small West African country of Sierra Leone. ..
In the 1960s and 1970s, a weak post-independence democracy was subverted by despotism and state-sponsored corruption. Economic decline and military rule followed. The rebellion that began in 1991 was characterized by banditry and horrific brutality, wreaked primarily on civilians. Between 1991 and 1999, the war claimed over 75,000 lives, caused half a million Sierra Leoneans to become refugees, and displaced half of the country's 4.5 million people. ... 

Conflict diamonds are diamonds that originate from areas controlled by forces or factions opposed to legitimate and internationally recognized governments, and are used to fund military action in opposition to those governments, or in contravention of the decisions of the Security Council.

  A well-structured 'Certificate of Origin' regime can be an effective way of ensuring that only legitimate diamonds -- that is, those from government-controlled areas -- reach market. Additional controls by Member States and the diamond industry are needed to ensure that such a regime is effective. These measures might include the standardization of the certificate among diamond exporting countries, transparency, auditing and monitoring of the regime and new legislation against those who fail to comply.
