We are a cutting house in Bedfordview, Johannesburg, not a shop in Bedfordview, and that is the point: you are buying at the level the trade buys at rather than from a retail counter. Everything ships insured overnight, and you can see the full grading report and video before you pay a cent.

No two diamonds are the same

A table describes a market, not a stone. Two diamonds identical on paper can differ by a third in price and both figures be right: how well the stone is actually cut and how much light it returns, where the inclusions sit and whether the eye finds them, how strongly it fluoresces, and how keenly that one happens to be priced against the international trade benchmark on the day. We check every stone against that benchmark before we show it to anybody, and the number that matters is the one quoted in writing on the stone you actually choose.

Captured 8 September 2026; guide figures rounded up to the next R100. Colour and clarity tables use sampled medians and percentile bands; rows without a measured range may use a limited lower-priced sample. Prices and availability can change. Your written quote identifies the actual stone and all inclusions.

Why the address is an office park, not a mall

Serious diamond businesses in South Africa mostly look like this one: a secure office, a safe, a desk and a cutting house, because that is what the goods require and what sharp pricing allows. A retail window adds theatre and margin; it does not add a better stone.

The Bedfordview model keeps the security tight, the overhead out of your price, and the conversation private, which is exactly how the trade itself buys. If you are after finished pieces rather than loose stones, the same bench handles jewellery in Johannesburg to order from this address.

What the office handles

  • Buying viewings, certified loose stones compared against their GIA reports at the desk, by appointment or video call.
  • Valuations and selling, the 48-hour valuation process with cleared funds within 72 hours after acceptance, FICA-compliant.
  • Quote comparisons, bring another dealer’s specification and the desk quotes it like-for-like.
  • Custom and re-mount work, engagement commissions and re-setting, with the centre stone cut on our own bench or sourced to order.
  • Collections and insured handover, in person at The Paragon or via Brink’s or G4S nationwide.

One operation, desk to bench

The reason Bedfordview can quote the way it does is structural: the dealer and the cutter are the same Etkind operation. Rough is bought at De Beers DBCM viewings and SA tender houses, cut and polished at Procut DCW, and sold at the desk upstairs from the work.

The cutter-direct page explains the arithmetic; the authority file carries the verifiable registrations, memberships and the paper trail for anyone who wants to check before they visit. Checking first is encouraged, it is exactly what we would do.

Visiting from outside Johannesburg

Half the desk’s clients never visit. The specification conversation runs on WhatsApp, viewings happen by video, and the stone or finished piece travels insured both ways. If you are in Gauteng, the appointment is usually the better experience, there is no substitute for grades compared in your own hand. Either way, the process, the certificates and the prices are identical.

Bedfordview office questions, answered

Where exactly is Prodiam in Bedfordview?

Suite F1W6, The Paragon, 1 Kramer Road, Bedfordview, Johannesburg. It is an office building, not a shopfront: you book an appointment, you are met, and the viewing happens at the desk with the loupe, the tweezers and the certificates out. The map entry is on Google under Prodiam Trading at The Paragon.

Why an appointment-only office instead of a jewellery store?

Three reasons: security, price and attention. Diamonds move between safes, not display windows, which keeps insurance sane and prices sharper. No retail floor means no retail overhead in your stone. And an appointment means the conversation is yours alone, with the stone, its certificate and the person who knows the goods, not a counter queue.

What happens at a Bedfordview appointment?

You sit at the desk, the stones come out against their GIA reports, and you compare grades in your hand under proper light. Buying conversations cover the specification, the firm ZAR quote and the setting route. Selling and valuation visits put your stone on the desk for the 48-hour valuation process. Nothing is rushed and nothing is owed for the conversation.

Do I have to come to Bedfordview to buy from Prodiam?

No. The Bedfordview office anchors the operation, but viewings also run by video call and WhatsApp, and finished stones and pieces travel insured nationwide via Brink’s or G4S with their certificates and a written insurance valuation on request. Clients buy across South Africa without ever visiting.

Is the cutting really done by the same operation?

Yes. The sister company, D and D Diamonds CC trading as Procut DCW, cuts stones on its own bench while Prodiam sources most to order, and has been a De Beers DBCM Emerging Beneficiation Customer since 2019. That is the point of the Bedfordview route: the dealer, the desk and the bench are one operation, which is why re-cuts, custom work and sharp like-for-like quotes all happen under the same roof.

How do I book, and what should I bring?

WhatsApp +27 74 702 1976 or use the contact form and pick a time. Buyers should bring their specification or budget thinking; sellers should bring the stone and whatever paperwork exists, certificates, invoices or old valuations. FICA requires identity documents when a sale concludes, so bring ID if you expect to transact.

Book the desk

One message books it. Bring the certificate if you have one, the question if you do not, and expect to leave knowing more about your stone than when you arrived.
