IDMA Code of Conduct & Bylaws

The International Diamond Manufacturers Association (“IDMA”), founded in 1946, is the leading organization representing the global diamond industry and all members of the worldwide network of diamond manufacturers and distributors. Our membership is comprised of the world’s leading diamond manufacturing organizations in every major diamond center worldwide.

Our association strives to promote and advance the interests of the diamond industry worldwide and to advance and support the interests of all of our industry’s many diverse worldwide stakeholders. We act as our industry’s responsible and respected voice on all international and domestic issues affecting the global diamond industry. While working to promote growth and profitability for our industry, we also remain dedicated to advancing our industry’s reputation and good standing and its many members.

IDMA is committed to legal compliance and maintaining the highest ethical practice standards in all business dealings worldwide. We believe that the reputation and integrity of diamonds mined, manufactured, distributed, and sold by members of our industry are essential to the future success, growth, and prosperity of the diamond industry and its many stakeholders.  

With these goals in mind, IDMA established this Code of Conduct. IDMA’s Code of Conduct applies to all IDMA member organizations and their respective members. It is intended to serve as a guide not only for IDMA members, but for all members of the international diamond industry in the conduct of their respective associations, in the conduct of the businesses of their individual members, and in carrying out the ethical, social, moral and legal responsibilities of all members of our industry in all of their dealings. We believe that these goals are best accomplished by building consumer trust and confidence in our members, by promoting honesty, economic advancement, quality, integrity, and transparency in the mining, manufacture, sale, and distribution of our products, and by playing an active and responsible role of leadership in our industry and our society at large.

  3. Engage in fair and ethical labor practices, including compliance with all applicable international and domestic labor laws, striving to address and overcome conflict in the world’s diamond-producing nations, treating all employees with respect and dignity, paying fair and reasonable wages and benefits to employees, promoting and maintaining safe, secure, appropriate and healthy living conditions and working environments for all employees, not allowing any member of our industry to be subjected to actual or threatened physical violence, oppressive working or living conditions, sexual, psychological or verbal harassment or abuse and refraining from discrimination, including, but not limited to discrimination based upon gender, race, religion, age, disability, sexual orientation, nationality, political opinion, or social or ethnic origin.
  4. Remain committed to the advancement of society and the world at large, including respect for human rights and democratic institutions, supporting policies and programs that promote human rights and the improvement of economic and living conditions in the diamond-producing and manufacturing nations of the world, by maintaining harmonious relations between the diamond industry and all other sectors of society at large, by being dedicated to raising standards of health, education, workplace safety and economic well-being in every sector of our industry, by supporting programs which encourage peace, security, diversity, social integration and economic and social advancement of all of the disadvantaged nations of the diamond industry, by promoting and advancing sustainable development of our world and by working to preserve and enhance the physical environment and the earth’s resources.
