Illegal trade in diamonds

Nature 
The illegal trade in diamonds and other precious stones is a key factor fuelling a number of conflicts, posing a special challenge to combating illicit trafficking and the activities of organised crime. Rebel and insurgency groups in control of diamond mining areas use diamonds to finance their war effort by exchanging the gemstones for arms and military support. In this way, bartered diamonds have been used to violate UN sanctions on procuring weapons.
