Diamond jewellery in South Africa, from the people who cut the diamonds.

The cutting house behind the jewellery

The reason this page leads with the diamonds rather than the designs is that the diamond is where most of the value, and most of the markup, sits. Prodiam is a South African diamond dealer and cutting house, directed by Darren Etkind, a member of the Diamond Dealers Club of South Africa bourse and licensed by the SADPMR; our sister manufacturer D & D Diamonds has been a De Beers DBCM Emerging Beneficiation Customer since 2019. We buy rough, we cut and polish it in-house at Procut DCW to GIA Excellent cut grade, and only then do we make jewellery from it. A high-street jeweller starts where we finish, buying in a polished stone or a finished piece and adding a retail margin. Starting one step earlier is what lets us price wholesale-direct rather than retail, and it is what lets us match stones, the perfect pair of earrings, the river of a tennis bracelet, in a way a shop buying stones in cannot.

What we make, the full range

Everything below is made to order, set with natural diamonds we have cut or matched ourselves, and priced on application. Each links through to its own page, where the design choices, the stone grades and the process are set out in full.

• Diamond engagement rings Bespoke engagement rings built around a single hero stone, solitaire, halo, three-stone or hidden-halo, cut in-house and set to your brief. →
• Wedding & eternity bands Diamond wedding bands and full or half eternity rings, with calibrated stones matched on the bench to sit flush against the engagement ring. →
• Diamond earrings Stud, halo and drop earrings, the two centre stones matched into a perfect pair within one colour and one clarity grade, the thing only a cutter can do. →
• Diamond pendants Solitaire, halo, three-stone, cluster and cross pendants on a matched chain, the centre stone supplied with its own GIA report. →
• Tennis bracelets Diamond tennis bracelets and line necklaces, every stone matched for colour, clarity and cut along the run so the line reads as one continuous river of light. →
• The ProJewel range Our fine-jewellery range and recent bench commissions, engagement rings, eternity bands, tennis pieces, earrings and pendants you can brief or take inspiration from. →
• Loose diamonds Certified loose stones currently on the bench, ready to buy on their own or to set into any of the pieces above. →
• Collections Curated one-off and themed pieces from the workshop, each made to order and priced on application. →

If you would rather begin with the stone than the setting, you can search our live diamond inventory and see fully-landed ZAR prices on GIA-certified natural diamonds, then have us set the one you choose.

Why buy diamond jewellery direct

The case for buying from the cutter rather than the counter comes down to three things, price, provenance and control:

• Price built up, not marked up, you pay a wholesale-direct stone price, referenced to the Rapaport list, plus transparent metal and making, instead of a single retail ticket with an opaque margin baked in. We quote firm, excl. VAT, before any work begins.
• One custody, fully traceable, the same house buys the rough, cuts it and sets it, so the diamond never leaves a documented chain. The certificate and a written insurance valuation travel with the finished piece.
• Stones matched, not just bought, because we grade on our own bench, we can match a perfect pair of studs, or every stone along a tennis line, within one colour and one clarity grade. A retailer buying stones in rarely matches this closely.
• Made to your brief, the shape, carat, colour and clarity range, design and metal are yours to set. Nothing is off-the-peg.
• Natural only, GIA primary, Prodiam works in natural, mined-Earth diamonds, certified by GIA or EGL, with GIA the primary laboratory.
