The Kimberly Process
The Kimberly Process is a system designed to eliminate conflict diamonds from all supply chains in the industry. This includes mining houses, cutters, diamond jewelry manufacturers and retailers. It was imperative that the cornerstone of African economies be protected while efforts to eliminate human rights abuses accelerated. The diamond industry took it upon themselves to comply with UN mandates and expand their efforts to fund clinics and treatments for HIV/AIDS patients, programs for orphaned children, and basic health care for over 5 million people. The system uses secure methods of transporting and accounting for all diamonds from its members. Because countries, such as the United States, only accept such controlled stones, you can be assured that you are purchasing conflict-free stones.
