For over a century, Mumbai has been the beating heart of India’s diamond industry — a city where tradition meets trade, and precision meets passion. The diamond market here isn’t just about commerce; it’s about craftsmanship, trust, and community. At the center of this thriving ecosystem stands the Mumbai Diamond Merchants’ Association (MDMA), a pioneer organization that has shaped the trade’s journey from small lanes of Kalbadevi to the grand corridors of the Bharat Diamond Bourse (BDB).
Trust is the true currency of the diamond trade. In an industry where each gem carries immense value, transparency defines success. The Mumbai Diamond Merchants’ Association (MDMA) has long championed this belief — setting standards that protect traders, ensure ethical practices, and maintain Mumbai’s status as a global diamond capital.
The future of India’s diamond industry depends not only on technology but also on talent. Recognizing this, the Mumbai Diamond Merchants’ Association (MDMA) has made skill development and knowledge sharing a central part of its mission.
