Mumbai has been connected to the global diamond trade for over a century, but the infrastructure that formalised that connection into a single world-class hub arrived in 2010 with the inauguration of the Bharat Diamond Bourse in the G Block of Bandra Kurla Complex. The BKC Diamond Market — as it is commonly referenced — is not a market in the street-shopping sense. It is the world’s largest diamond exchange, spread over 20 acres and 2 million square feet of constructed area across 26 towers, each nine floors high. The numbers are extraordinary: over 4,000 member offices representing traders from more than 100 countries, daily footfall of 45,000 to 50,000 people, handling of approximately 90 percent of the world’s polished diamond trade at its peak, and a customs clearance facility within the complex that processes diamond imports and exports without the goods leaving the building.
For the global diamond industry, BKC is not a destination — it is the destination. For Mumbai’s commercial landscape, the Bharat Diamond Bourse is BKC’s most globally significant institution.

Where Exactly Is BKC Diamond Market
The Bharat Diamond Bourse is located in G Block of the Bandra Kurla Complex, on Trident Road, Bandra East, Mumbai 400051. BKC is Mumbai’s primary planned business district — the financial address that houses the Reserve Bank of India’s regional office, the Securities and Exchange Board of India, major Indian and international banks, and the headquarters of numerous multinational corporations. The G Block, which BDB occupies exclusively, is in the eastern portion of the complex.
Bandra Kurla Complex Metro Station on Mumbai Metro Line 3 (the Aqua Line, underground, inaugurated October 2024 by Prime Minister Narendra Modi) opened F Block BKC to underground transit connectivity for the first time, making the complex accessible from Santacruz Airport, Bandra, Worli, Dharavi, Sion, and Cuffe Parade on the same line. This metro connectivity represented a significant improvement for the tens of thousands of daily workers in BKC who previously relied entirely on road transport. The station address is F Block BKC, Sant Dnyaneshwar Nagar, Bandra East.
For the BDB specifically, vehicular access is via the Western Express Highway, entering BKC at the main entrance and following internal signage to the G Block. The complex has substantial internal parking. The BKC-Bandra Kurla Complex metro station is within BKC and requires a short walk within the complex to reach the G Block. Taxis and cabs navigate reliably to BDB’s Gate No. 4 entrance.
What Happens Inside BKC Diamond Market
The Bharat Diamond Bourse is a member organisation — a non-profit company registered in 1984 and made operational in 2010 — and its trading floors are accessible to members and their guests rather than to the general public on a walk-in basis. Visitors must schedule appointments in advance through the BDB Visitor app, which allows individuals to request meetings with member offices. Without a prior appointment through this system, entry to the trading complex is not possible.
Within the complex, the scale of diamond commerce that operates daily is genuinely staggering. Rough diamonds from mining operations in Africa, Russia, Canada, and Australia arrive for sorting and valuation. Polished diamonds — India processes approximately 90 percent of the world’s cut and polished diamonds, primarily in Surat and Mumbai — are bought and sold in lots ranging from small melee stones to large individually valued pieces. Natural coloured diamonds in every shade from canary yellow to deep blue are traded by specialist dealers whose entire business is built around a single colour category.
The infrastructure supporting this commerce within BDB includes four walk-in vaults, 24,500 safe deposit boxes, a 580-square-metre trading floor, dedicated customs clearance facilities (approximately 12,000 square feet of customs area and 7,000 square feet of clearing agent space), commercial banks, insurance companies, gemological laboratories, restaurants, stationery, and travel agents. The complex essentially functions as a self-contained diamond city where a trader can import, insure, store, certify, sell, and export diamonds without leaving the building.
For individual jewellery buyers or retail consumers looking to purchase diamond jewellery, the BDB’s individual member offices — accessible by appointment — can facilitate such transactions, but the Bourse is not structured as a consumer retail destination in the way that jewellery markets in Zaveri Bazaar or Panchratna operate. Serious individual buyers seeking loose polished stones or specific diamond specifications can arrange appointments with member traders directly.
Nearby Areas Worth Visiting
BKC as a business district has developed significant food infrastructure over the years. The Bandra area — Bandra West’s Hill Road, Linking Road, and the café-restaurant belt — is accessible by the new Metro Line 3, turning BKC into a practical starting point for both business and leisure in the same visit. Bandra Bandstand, the promenade along the Arabian Sea in Bandra West, is one of Mumbai’s most pleasant evening walks. The American Consulate General is in BKC. The planned Mumbai–Ahmedabad bullet train terminus at BKC — scheduled for 2029 — will eventually make the complex India’s most transit-connected commercial zone.
