IDMA
Board Members

Throughout its 77-year history, IDMA’s board members have represented the interests of their countries’ manufacturing hubs, i.e., securing a steady and reliable supply of rough diamonds. IDMA’s current role is to protect the integrity of the diamond supply pipeline, to engage in dialogue with producing countries, producers, rough diamond traders, technology providers, financial services, and NGOs, all to ensure that diamond manufacturers, large and small, will continue to fulfill their crucial role in the supply chain. The IDMA Board looks forward to welcoming additional diamond manufacturing hubs to its ranks.
