Even though the Kimberley Method is moderately thriving in restricting the number of conflict diamonds moving into the industry, some however locate their way in. According to the Intercontinental Diamond Makers Association, conflict diamonds represent two–3% of all diamonds traded.[141] Two big flaws nevertheless hinder the usefulness of your Kimberley Approach: (1) the relative simplicity of smuggling diamonds throughout African borders, and (two) the violent character of diamond mining in nations that are not inside of a complex state of war and whose diamonds are consequently regarded as "thoroughly clean".[a hundred and forty]
