Concentration2024
The world's diamonds are mined in a few places but cut in essentially one: Surat, in the Indian state of Gujarat, where roughly 90% of all diamonds are cut and polished, employing hundreds of thousands of workers. Kiran Gems is the largest cutting-and-polishing company there. So after the rough-supply chokepoint (Alrosa and De Beers), the diamond chain narrows again to a single city — nearly every diamond on Earth passes through Surat to be turned from rough into a finished, sellable stone. The supply chain is doubly concentrated: at the mine (Russia and Africa) and at the cutting wheel (India), in completely different countries, with Surat the indispensable midpoint that almost no one outside the trade could name.

Surat's near-monopoly on cutting makes the global diamond trade hostage to that one place — and tightly coupled to the rough-supply politics upstream. When Russian rough was sanctioned, it was Surat's cutters, including Kiran Gems, who absorbed the shock, because they process the stones regardless of origin and depend on rough flowing in. So a finished diamond's journey wires Russian and African mines to a single Indian manufacturing cluster, and a disruption at either end — a sanction or downturn upstream, or a local crisis in Surat — propagates through the whole chain. It also makes the diamond industry a major employment and economic dependency for one region: the polished-diamond market and a huge Indian labor base rise and fall together, an exposure invisible in the finished gem on a ring.
