A blood diamond, also known as a conflict diamond, is a diamond that came from an area which is controlled by armed groups which oppose the rules and regulations of governments. These diamonds are mined by civilians who have been ordered by the armed groups to do so (most of them are children), and typically if they refuse to do the work they may be possibly raped, abused, or even murdered. The diamonds are then sold and used to buy weapons to help the armed groups fight against the government. Because of this, most of the blood diamond mining happens in war zones. This is a form of exploitation. They are traded illegally. There have been 3.7 million deaths over diamonds. The Kimberly Process Certification Scheme(KPCS) helps keep blood diamonds out of markets, although most of these diamonds are assumed to be legitimate it is difficult to tell with all of the smuggling. Over 80 (81) countries participate in the KPCS. Every KPCS certified diamond has to be labeled with a specific government number.
