The Demand Gap
A Record-Breaking Building, Fully Sold — Still Waiting on Buyers
Surat Diamond Bourse is the Guinness World Record holder for the largest office building on Earth — larger than the Pentagon, spanning 35 acres, 9 towers, and over 66 lakh sq ft, with 4,500+ offices and India's largest diamond customs house built in.
Every office sold out. But today, only a fraction operate at full activity, because international buyer footfall hasn't caught up to seller capacity yet. That gap is not a flaw in SDB — it's an opening.

Our Commitment to You
We Handle the Logistics. You Handle the Deal.
International buyers hesitate to visit Surat for one reason: uncertainty about logistics in an unfamiliar city. Our entire job is to remove that uncertainty — before, during, and after your visit.
Every Detail Planned Ahead
We review your buying category and dates, match you with vetted manufacturers, and build a single itinerary — flights, hotel, and meetings — before you leave home.
A Dedicated Host, Start to Finish
A VisitSDB team member is with you throughout — from airport to trading floor — handling transport, translation, and scheduling so nothing falls through the cracks.
The Relationship Doesn't End at Departure
We stay in touch with the manufacturers you met, so your next visit — or your next order — starts from a relationship, not a cold introduction.
Where Are You Buying From Today?
See What Changes When You Source Direct
Mumbai, Hong Kong, Dubai, Antwerp, and New York are all major diamond trading centers — but none of them is where the diamonds are actually cut. Tap a market to see how it compares to sourcing direct in Surat.
Mumbai
Mumbai Trades Them. Surat Cuts Them.
Bharat Diamond Bourse (BDB) in Mumbai's Bandra-Kurla Complex is the world's largest diamond bourse by membership and the commercial heart of India's diamond trade — home to thousands of trading offices, the Customs House, and the banks that finance the industry.
- Skip the Trading Margin. Stones traded in Mumbai have typically already moved from manufacturer to trader. Buying in Surat means transacting with the manufacturer directly.
- Minutes From Mumbai, Not a New Continent. Surat is a short domestic flight or a few hours by road from Mumbai — this isn't a new market to learn, it's the same industry, one step closer to the source.
- The Same Trust, Fewer Steps. India's regulatory and customs framework applies in both cities. What changes is how many parties are between you and the stone.
We also host buyers from established and emerging markets beyond these five — including Israel, Vietnam, and Latin America.
