Until mid 2007, the DDII Coordinating Group included Partnership Africa Canada, the Foundation for Environmental Security and Sustainability, Global Witness, De Beers, the Rapaport Group, the International Diamond Manufacturer's Association and the Communities and Small-Scale Mining Secretariat of the World Bank (CASM). In June 2007, the coordinating group gave way to a new Board of Directors and a larger Advisory Group.

DDII is incorporated as a non profit organization in the United States, in the District of Columbia, and is registered with the National Revenue Service as a 501c3 charitable organization. DDII is envisaged as the centre of an organization that will encourage affiliates in different countries where there is interest in its aims and objectives. These may, in time, include existing non-profit organizations, or they may be stand-alone affiliates operating exclusively under the DDII label. DDII Canada is currently being incorporated. DDII will establish quality standards for all projects, publications and organizations working under the DDII name.
