Procut Diamond Cutting Works
Diamond cutting in Johannesburg, from the bench.
Procut DCW does diamond cutting in Johannesburg as the in-house manufacturing arm of Prodiam, trading name of D and D Diamonds CC. We are working diamond cutters in South Africa, a Bedfordview diamond manufacturer doing in-house cutting and diamond polishing on our own benches. A De Beers DBCM Emerging Beneficiation Customer since 2019, we cut every stone Prodiam Trading sells.
Diamond beneficiation, proudly South African
D and D Diamonds CC (Reg. 2002/018001/23), trading as Procut DCW, is a proudly South African beneficiation company. We hold a Beneficiation Licence under the Diamonds Act 1986. Every rough parcel that arrives at the bench is Kimberley Process documented. Most rough is South African-mined, sourced through DBCM viewings, the State Diamond Trader, and SA tender houses; the source of any individual parcel is identified on the rough invoice and made available to the buyer of the polished stone on request.
Goods are sourced directly from De Beers viewings in Johannesburg, from tender houses in Kimberley, Wolmaransstad, and Schweizer Reneke, and from the State Diamond Trader. We maintain long-standing relationships with independent diggers nurtured over twenty years. The rough purchased moves directly to our cutting benches in Bedfordview. No middlemen. No markups. No provenance gaps.
Training the next generation
At Procut Diamond Cutting Works we take pride in providing opportunities to previously disadvantaged South Africans. By equipping them with internationally recognised diamond polishing skills, we secure their financial futures and contribute to the long-term beneficiation of the South African diamond industry.
This is not a marketing position. Maintaining a SADPMR-inspected manufacturing facility staffed by skilled SA diamond polishers is a condition of our DBCM EBC status. The economic uplift to the country is built into the contract.
What our diamond cutters in South Africa produce
Polished diamonds from 0.30 to 10 carats, in many shapes, colours, and clarities. Every stone polished to GIA Excellent cut grade, the highest cut grade available, which maximises brilliance, fire, and scintillation. We also offer repolishing services to GIA specification or to customer requirements, and recutting of inherited or insurance-replacement stones.
Why this matters for what you buy
Most diamond buyers in South Africa transact through layers of wholesalers, each adding a margin. When you buy from Prodiam, you buy from the manufacturer. We cut them. You pay wholesale. That is a logistical fact, not a marketing line. Every step from the De Beers viewing room to your hand happens inside the Etkind operation.

The official Procut DCW website
Procut DCW maintains its own manufacturing-side website at procutdcw.co.za. That site is the cutting works seen from the bench: rough-buying, the cutting floor, the SADPMR audit trail, the EBC contract. This page (prodiam.co.za/procut/) is the same operation seen from the retail side, where the polished stones meet the customer. Same legal entity, same address, same director, different vantage point.
Diamond cutting in South Africa, common questions
Where are diamonds cut in South Africa?
South African diamond cutting is concentrated in Gauteng, mostly within a few streets of Bedfordview, Johannesburg, around the De Beers DBCM rough-viewing rooms. That is where Procut DCW, the cutting works behind Prodiam, polishes its stones. A handful of cutting houses also operate near Kimberley and Cape Town, but the bulk of SA diamond manufacturing happens in Johannesburg, which is why the cutter-direct route starts there.
Does Prodiam cut its own diamonds?
Yes. Every Prodiam stone is cut and polished in-house at Procut DCW, the trading name of D and D Diamonds CC, at our Bedfordview bench. We are a working diamond manufacturer, not a reseller buying finished goods. Rough is bought at De Beers DBCM viewings and SA tender houses, then cut on our own benches to GIA Excellent grade. Buying from Prodiam means buying directly from the diamond cutter.
What is the difference between diamond cutting and diamond polishing?
Cutting shapes the rough crystal into the diamond outline and facet pattern; polishing brings each facet to its final mirror finish on a spinning scaife. In practice a diamond cutter does both, and the trade often uses "cutting" to mean the whole manufacturing process. At Procut DCW in Johannesburg we cut and polish on the same bench, finishing to GIA Excellent cut grade, the highest grade available.
Can you repolish or recut an old diamond?
Yes. As a working South African diamond manufacturer, Procut DCW repolishes tired or damaged stones to GIA specification and recuts inherited or insurance-replacement diamonds where a recut improves the grade or removes surface damage. The stone is assessed on the bench first; we only recommend a recut when the yield and grade gain justify it. Repolishing and recutting are quoted per stone on application.
What is diamond beneficiation, and why does it matter?
Beneficiation means adding value to rough diamonds inside South Africa, cutting, polishing and finishing them here rather than exporting the rough. Procut DCW is a licensed beneficiation company and a De Beers DBCM Emerging Beneficiation Customer since 2019, which is why it can buy rough at the source. For a buyer, beneficiation is what makes the cutter-direct, wholesale price possible: the value is added at our bench, not a foreign one.
Are you a registered diamond cutting and polishing works?
Yes. Procut DCW operates as a licensed SA diamond manufacturer under a Beneficiation Licence per the Diamonds Act 1986, with a SADPMR-inspected cutting facility in Bedfordview. Every rough parcel is Kimberley Process documented and the source recorded on the rough invoice. The same building houses the GIA South Africa office, so independent grading is a few doors from the cutting bench.
