Mumbai — India's Diamond and Coloured-Stone Trading Capital
Mumbai — India's Diamond and Coloured-Stone Trading Capital
The Bharat Diamond Bourse, the Zaveri Bazaar, and the city's role in processing approximately 90 per cent of the world's polished diamonds
Mumbai — formerly Bombay — is India's principal centre of diamond cutting, trading, and jewellery export, handling approximately 90 per cent of the world's polished diamond production by piece count and a substantial share of the global coloured-stone trade. The city's central role rests on the combination of established workforce skills (particularly in the diamond cutting tradition that developed in the second half of the twentieth century in nearby Surat), strong commercial infrastructure (the Bharat Diamond Bourse opened in 2010 as the world's largest diamond trading complex by floor area), favourable government policy (including export incentives and special economic zone designations for the diamond industry), and the broader weight of India's traditional position in the gem trade. The Mumbai diamond and coloured-stone trade represents one of the largest single concentrations of gem-trading activity in the world.
Historical background
Mumbai's emergence as the principal Indian gem trading centre dates to the second half of the twentieth century, with the diamond cutting industry developing initially in nearby Surat and the trading and finishing operations consolidating in Mumbai. The Indian diamond industry rose rapidly through the 1970s and 1980s on the basis of low-cost skilled labour, with the Surat cutting workshops able to process small diamonds (under one carat) at prices that displaced other competing cutting centres. By the 1990s, India had become the dominant cutter of small diamonds, and Mumbai had emerged as the principal trading and export hub for the finished goods.
The traditional Indian gem trade — handled in the Zaveri Bazaar and other historic commercial districts — predates the modern diamond industry and continues to operate alongside the more recent industrial development. The combination of the historical trade and the modern diamond industry has produced a uniquely diverse gem trading environment, with operations ranging from small family firms in the historic bazaars through international diamond trading houses in the modern Bharat Diamond Bourse complex.
The Bharat Diamond Bourse
The Bharat Diamond Bourse (BDB), opened in 2010 in the Bandra-Kurla Complex of Mumbai, is the world's largest diamond trading complex by floor area, housing over 2,500 traders, cutters, and brokers under one roof. The complex provides secure trading offices, vault facilities, banking services, gemological laboratories, customs facilities, and the broader infrastructure required for international diamond commerce. The BDB consolidated what had previously been a fragmented Indian diamond trade scattered across multiple commercial districts, providing a single internationally accessible facility comparable to the major diamond bourses of Antwerp, Tel Aviv, and New York.
The BDB operates under the Bharat Diamond Bourse organisation, which is one of the constituent members of the World Federation of Diamond Bourses. Membership is restricted to companies meeting the trade's compliance and integrity standards, with the bourse functioning both as physical infrastructure and as a self-regulating trade organisation. The BDB has been instrumental in supporting the formal organisation of the Indian diamond trade and in providing the international counterparties with confident trading partners in the Indian market.
The Zaveri Bazaar and historic districts
The Zaveri Bazaar — literally jewellery market in Hindi — is the historic Indian gem and jewellery trading district of Mumbai, located in the central commercial area of the city near the Crawford Market and the Bhuleshwar district. The Zaveri Bazaar has been the centre of Indian jewellery commerce in Mumbai for over a century, with thousands of small and medium firms operating from the dense network of small offices and shops that fill the district. The traditional trade handles both diamonds and coloured stones, with substantial activity in gold jewellery manufacture, antique and estate jewellery, and the broader Indian wedding and bridal jewellery market.
The Opera House district, located in south Mumbai near the historic theatre of the same name, is another principal commercial centre for the Indian gem and jewellery trade. The district has a particular concentration of coloured-stone wholesale and retail operations, with significant activity in ruby, sapphire, emerald, and the broader coloured-stone trade. The combination of the Zaveri Bazaar, the Opera House district, and the modern BDB complex provides Mumbai with multiple distinct trading environments serving different segments of the broader gem and jewellery market.
The relationship with Surat
Mumbai's role as the principal trading and export hub is closely connected to Surat's role as the principal cutting centre. Surat, located approximately 270 kilometres north of Mumbai in Gujarat state, processes the bulk of the small diamond cutting that supports India's dominant share of the global polished diamond market by piece count. Rough diamonds are imported through Mumbai (which serves as the principal Indian customs port for the diamond trade), shipped to Surat for cutting, and returned to Mumbai for sorting, grading, trading, and export. The two-city system has been the backbone of the Indian diamond industry for several decades and continues to underpin the country's dominant position in the global cutting trade.
The coloured stone trade
Beyond the diamond trade, Mumbai is also a substantial centre for coloured-stone commerce. The Opera House district and the Zaveri Bazaar both handle significant volumes of ruby, sapphire, emerald, and the broader coloured-stone trade, with operations ranging from small dealer offices to substantial wholesale and import-export firms. The coloured-stone trade in Mumbai serves both the domestic Indian jewellery manufacture (the Indian wedding jewellery market is one of the world's largest) and the international wholesale market, with significant Indian operations playing important roles in the global supply chain for many coloured stone categories.
In the trade
For Skyjems and the broader trade, Mumbai is one of the most important global centres for sourcing diamonds and coloured stones. The combination of large-scale supply, competitive pricing, and well-established commercial infrastructure makes Mumbai a primary destination for international buyers seeking access to the broad range of Indian-cut and Indian-traded material. The trading infrastructure (BDB, Zaveri Bazaar, Opera House) supports both formal large-scale commercial transactions and the more informal trading relationships that have been the historical foundation of the Indian gem trade. The city's continuing development as a global gem trading centre reflects both the broader growth of the Indian economy and the specific structural advantages that have made India the world's principal diamond cutting nation.
