Membership in CIBJO is not open to individuals, but rather to national associations active in the jewellery and gemstone industries, and international associations, corporations and service providers in the jewellery industry.
The highest decision-making body is the General Assembly of Delegates, which meets at CIBJO Congresses at least once every second year. Each of the member organisations is entitled to vote, although voting is by a weighted system, with two third of voting assigned to national trade association members and one third of voting assigned to commercial, international and service organisations.
National Association membership is open to all professional organisations in the jewellery and gemstone sectors, regardless of the country they are located in. In the event of that several associations exist, they may all be equally represented in CIBJO, after applying for membership and being approved by the Executive Committee. In the event that more than one organization participates in the delegation from a particular country, the leadership role is decided by the entire delegation.
Each country appoints representatives to participate in three distinct sectors, or areas, of interest, they are: Sector A (Gem Materials, Trade and Laboratories), Sector B (Jewellery Distribution) and Sector C (Jewellery Manufacturing/Technology/Precious Metals);
Commissions may be formed to focus on specific topics of interest, and they may cover more than one such sector. Active commissions include the Diamond Commission, the Coloured Stone Commission, the Pearl Commission, the Gemmological Commission, the Marketing and Education Commission, the Precious Metals Commission, the Ethics Commission, and the Association Executives Networking Commission.
