India Cuts 90% of the World's Diamonds — And Most of Them Come From Africa
For most of the 21st century, the global diamond industry has run a simple, consistent route: mined in Africa, sold through London or Antwerp, cut in Surat, retailed in New York. Surat, in Gujarat, processes roughly 90% of the world's natural diamonds by carat weight, and the overwhelming majority of that rough material comes from African producers — Botswana, South Africa, the DRC, and Angola chief among them.
India isn't a diamond-producing country; it hasn't been since the early 1900s. What it has instead is an extraordinary cost advantage in cutting and polishing — commonly cited around $10 per carat in India versus well over $50 per carat for equivalent work done in Africa itself. That gap, more than anything else, is why the pipeline exists in its current shape, and why more than 4.5 million people work directly in Surat's diamond trade, with over 10 million more connected to it indirectly, in a workforce that's roughly 60% women in the polishing segment specifically. Surat's polished diamond exports run over $60 billion annually against more than $20 billion in rough diamond imports.
Why Botswana specifically anchors this relationship
Botswana is Africa's leading diamond producer, and India is already its largest diamond trading partner — not a new relationship, an established one. Indian firms including Shrenuj, Blue Star, and KGK Diamonds have run offices and cutting operations in Botswana for years, and the two countries jointly established the India-Africa Diamond Institute back in 2008 specifically to train local workers in cutting, polishing, and grading — an attempt, only partly successful so far, to capture more of the value chain locally rather than exporting all the rough stone.
2026 is a genuine crisis year, not a routine one
The natural diamond industry is in real trouble, and it isn't cyclical this time. Lab-grown diamonds now account for roughly a fifth of the global diamond market, up from about 1% a decade ago, with some forecasts projecting continued sharp growth. Debswana, Botswana's state diamond company, has cut production by somewhere between a third and 40% depending on which recent reporting period you look at, with flagship mines at Jwaneng and Orapa facing temporary multi-month closures. Diamonds account for roughly a quarter of Botswana's GDP and close to 75% of its foreign exchange earnings, so a slump of this scale isn't a company problem — it's a national one; projected diamond revenue for the fiscal year ending this September is expected to come in at less than half the historical average. New 2026 US tariffs have added further disruption specifically to the India-based polishing trade that Botswana depends on to convert its rough stone into sellable value.
The pivot: Botswana leaning further into India
This is what makes the story current rather than just a crisis recap: Botswana has begun actively exploring a deeper, more central partnership with India specifically, not as a brand-new relationship but as a recalibration of an existing one. The logic, per analysts covering the shift, is that India offers a diversified, purely commercial downstream market without the political strings or debt-based conditionality that other financing partnerships can carry — an unusually comfortable option for a country wary of new dependency. Some rough diamond sales are also increasingly routing through Dubai's DMCC free zone, partly for tax efficiency and proximity to Surat's cutting centers, a sign the entire trade geography is genuinely in motion right now, not settled.
What this means if you're in the industry
For anyone sourcing, cutting, or trading between India and Africa, 2026 is a moment of real structural change: a shrinking natural-diamond pie overall, a real opportunity for closer India-Africa integration as Western-centric trade routes get questioned on cost and politics alike, and genuine pricing and volume uncertainty that makes long-term contracts riskier than they'd have been five years ago.
Note: production-cut and stockpile figures for Debswana vary meaningfully depending on the reporting window and source — this article uses ranges rather than single precise figures for that reason. The India-diamond trade is moving quickly in 2026; confirm current numbers before relying on this for a real trade or investment decision.
