Diamond mining in South Africa
Crews have been digging South Africa's diamond fields since 1867, and there is plenty of ground left to work. AMIQ keeps tabs on the 40-plus projects live right now, whether they sit in the kimberlite pipes ringing Kimberley or along the Orange River alluvial diggings, and pins down who owns, engineers and builds each one. Show up first and the contract is yours to lose.
Better than 40 live diamond projects on the South African map
The four routes a South African diamond travels
Few countries recover stones in as many ways at once. Some are blasted loose from deep kimberlite pipes, others washed out of river gravels, more dredged off the seabed, and a handful hauled up from massive underground operations. Each route feeds its own run of active projects, and that is what AMIQ follows.
Around Kimberley, volcanic pipes plunge to roughly 2.5 km and hold the country's richest stones. These kimberlite pipes are where South African diamonds first came from, and they still carry the biggest mines on the books.
Crews still pull alluvial diamonds from the southern banks of the Orange River, where stones worn loose from inland pipes come to rest in the gravels. Work like this leans on earthmoving, screening and gravity-recovery contractors.
Stones turn up offshore too, lodged in seabed gravels and along the shoreline off the north-western coast. Pulling them out calls for purpose-built dredging gear, vessels and offshore processing.
In Limpopo, De Beers' Venetia tops the national output at roughly 3 million carats every year. A move underground is set to keep it running to about 2046, which keeps a long queue of development and engineering work in play.
Explore →Over in the Northern Cape, Petra's Finsch turns out close to 2.1 million carats, and near Pretoria the historic Cullinan Mine is where the largest gem diamond ever found surfaced back in 1905. Both are deep, long-life pipes with plenty of work still ahead.
Explore →De Beers and Petra Diamonds sit at the front of South African output, with Alexkor, BlueRock, Diamond Corp and a few others filling in behind them. What they choose to build, expand and re-treat is what drives the buying across the diamond fields.

One subscription unlocks all 40-plus diamond projects in the country, and behind every one sits the checked mine-owner, engineer and EPC name you need to open the conversation while it still counts.
Which mines still sit on the deepest reserves
The size of a resource tells you roughly where the decades-long work will be. Lined up by the carats left underground, these are the operations most likely to keep ordering development, plant and service contracts for years to come.
What AMIQ does for a diamond supplier
Recovery plants, dense-media separation, X-ray sorting, security, dredging, earthmoving, freight. Whatever your firm carries to a diamond operation, winning the work comes down to two answers: which projects are moving, and who holds the purse strings.
Arrive ahead of the tender. Filter by scope, phase and place to land on diamond projects while their specs are still taking shape, well before anything reaches a public tender notice.
A person to call, not a front desk. Go straight to the mine owner, project engineer, EPC firm and the suppliers already on site, with each record confirmed and refreshed by the people who research it.
A nudge the moment something changes. A text or email reaches you as soon as a fresh project is logged or an existing one moves to its next stage, so nothing gets past you while your crew is heads-down on a job.
We go where the stones go. Pipe, river or seabed, from Kimberley and Cullinan through to the Orange River diggings and the offshore coast, if the diamonds are there, the projects are on our list.
Made for the people who supply the mines. Development and earthmoving outfits, recovery-plant and dense-media specialists, X-ray sorting, security and freight businesses all lean on AMIQ to find their next diamond customer.
One file for the whole picture. Every one of the 40-plus diamond projects lives in a single searchable system, sitting inside a wider library of 560-plus South African projects and more than 2,200 right across Africa.
The country where diamond mining in South Africa was born
One stone started everything. The Eureka Diamond, picked up beside the Orange River in 1867, touched off a rush that flung open South Africa's diamond fields and grew into an industry that, more than 150 years on, still puts the country among the world's top five producers.
The best ground is the kimberlite pipes near Kimberley in the Northern Cape, volcanic conduits that took shape around 3.3 billion years ago and ferried diamonds upward from far below the surface. Following those pipes down, while also working the Orange River alluvial diggings and the marine deposits offshore, hands South Africa a range of diamond sources that few other places can match.
A small group of large mining companies does most of the producing: in 2017 Venetia and Finsch between them accounted for over 60% of the country's diamonds. For a supplier, that spread of pipes, diggings and marine work is exactly where the openings are. Sign up to AMIQ and the per-project capital values, plus the confirmed mine-owner, engineer and EPC contacts on each, come into view.
The provinces where the diamonds turn up
The country's diamond story plays out across four provinces. Each leans on a different sort of deposit, from inland kimberlite pipes through to river-gravel diggings, and each fields its own roster of projects.
Northern Cape
This is where Kimberley sits, the cradle of the modern diamond trade, along with Petra's Finsch mine. The kimberlite pipes here still carry a large slice of the country's diamond output.
Explore →Limpopo
Limpopo is home to De Beers' Venetia, the biggest diamond producer in the country. The shift underground stretches its life out to about 2046, which feeds a long run of development and engineering work.
Explore →Gauteng
Just outside Pretoria in Gauteng lies the historic Cullinan Mine, the pit that produced the largest gem diamond ever found, back in 1905. It is still a long-life pipe with plenty of development ahead.
Explore →Free State
Across the Free State, alluvial diggings sift the river gravels where stones worn out of inland pipes have come to rest. That kind of work suits earthmoving, screening and gravity-recovery contractors.

Diamond mining in South Africa: what suppliers want to know
How many diamond mining projects are there in South Africa?
On the AMIQ books there are 40-plus diamond mining projects in South Africa, both running and planned, set within a wider library of over 560 projects nationwide. They cover every stage and source, kimberlite pipes, alluvial diggings and marine recovery alike, and stretch through the Northern Cape, Limpopo, Gauteng and the Free State.
Where are diamonds mined in South Africa?
Most stones come out of the kimberlite pipes ringing Kimberley in the Northern Cape, Petra's Finsch mine among them, and from De Beers' Venetia over in Limpopo. The Orange River yields alluvial diamonds, the historic Cullinan Mine sits just outside Pretoria in Gauteng, and more stones are lifted off the north-western coast.
What are South Africa's biggest diamond mines?
The largest are Venetia in Limpopo, which leads the country at roughly 3 million carats a year, then Petra's Finsch mine in the Northern Cape and the historic Cullinan Mine near Pretoria. Venetia, Finsch and Cullinan are each long-life kimberlite pipes carrying deep underground development ahead of them.
Who mines diamonds in South Africa?
The big names are De Beers, behind Venetia and the Cullinan legacy, and Petra Diamonds, which works Finsch and Cullinan, with Alexkor, BlueRock, Diamond Corp and a handful of others alongside them. Together they hold most of the pipe, alluvial and marine operations, and what they buy is what shapes demand for suppliers.
What is a kimberlite pipe?
A kimberlite pipe is an old volcanic conduit that brought diamonds up from far below the surface. The ones around Kimberley took shape some 3.3 billion years ago and run to about 2.5 km down, holding the richest diamond ground in the country. Working them that deep creates demand for specialised development, hoisting and recovery services.
How can suppliers find new diamond mining projects in South Africa?
They turn to Africa Mining IQ to catch South African diamond projects early, before the specs close. Every entry sets out its scope, stage and place, names the checked owner, engineer and EPC firm, and triggers an email or SMS the moment a fresh diamond project is logged or an existing one changes.
