Diamond wedding rings made to order in South Africa

The bench behind the band

A wedding ring is the one piece of jewellery most people wear every day for the rest of their lives, so where it is made matters more than for almost anything else they will buy. Most wedding rings in South Africa pass through several hands, a cutter, a wholesaler, a retailer, before they reach a counter, each adding a margin.

Prodiam is the unusual case where a single house runs the whole chain. We buy rough diamonds at De Beers DBCM viewings and South African tender houses, cut and polish them in-house at Procut DCW to GIA Excellent cut grade, and set them into finished bands on our own Bedfordview bench, directed by Darren Etkind.

A high-street jeweller begins at the point we have already reached, buying in a polished stone or a finished band and adding a retail margin on top.

Starting one step earlier is what lets us price direct rather than across a retail counter, and it is what lets us match a band’s stones to the side diamonds already in your engagement ring, the thing a shop buying stones in simply cannot do.

Every kind of wedding ring we make

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

• Diamond wedding bands & eternity rings Diamond-set bands in channel, shared-claw, U-set and pave, full or half eternity, every stone matched on the bench within one colour and one clarity grade. →
• His & hers wedding rings Two rings designed together as a matched pair, hers usually diamond-set and slimmer, his cleaner and wider, balanced in the same metal and finish. →
• Diamond eternity rings Full and half eternity bands of calibrated diamonds matched the whole way round, as the wedding ring itself or as an anniversary upgrade. →
• Engagement ring & wedding band together The bridal set: engagement ring and matching wedding band designed as one, in one metal lot, so they sit flush and read as a single piece. →

If the wedding ring is going on alongside a ring you have not chosen yet, start with our custom engagement rings and have the band designed in the same breath. And if you would rather begin with the stone than the setting, you can search our live diamond inventory and see fully-landed ZAR prices, then have us set the one you choose. Not sure which band is right?

Metal: why it matters on a ring worn every day

The metal is the foundation of a daily-wear ring, and the choice is about colour, weight and longevity rather than quality, both options here are precious and hallmark-grade. Match the wedding band to the metal of the engagement ring it sits against, ideally from the same lot, so the two read as one and wear at the same rate.

• Platinum, dense, naturally white and the most hard-wearing choice. It never needs re-plating, develops a soft patina rather than wearing thin, and sits with a reassuring weight on the hand. The classic choice for a band meant to outlast everything.
• 18k white gold, lighter than platinum and rhodium-plated for a bright white finish that is refreshed occasionally over the years. A practical match for a white-gold engagement ring at a lighter weight.
• 18k yellow gold, the warm traditional tone, kind on most skin and unmistakably gold. Holds its colour without plating and suits a classic or vintage-leaning ring.
• 18k rose gold, the copper-warmed blush that flatters a wide range of skin tones and reads softer than yellow. A distinctive choice that pairs beautifully with warm-toned diamonds.

Matching the band to the engagement ring

The single most common wedding-ring request we get is to make a band that sits perfectly against an engagement ring, and getting it right comes down to three things a cutting house controls and a counter does not.

First, the profile: the band is shaped so it meets the engagement ring flush at the shoulder, with no gap and no spinning, sometimes a straight band, sometimes a gentle curve cut to nest around a halo or a raised setting.

Second, the metal lot: making both in the same metal, and where possible from the same casting lot, means the colour and finish are identical rather than a near-match. Third, the flush fit of the stones: where the band is diamond-set, we match its diamonds to the engagement ring’s side stones within one colour and one clarity grade, so the pair reads as a single piece under light.

If we made the engagement ring, the original CAD file is on record and the match is exact. For a ring and band designed together from the outset, see the engagement ring and wedding band as a set.

Diamond wedding bands: subtle accents, half or full eternity

A wedding band is one of three things, and the right one depends on the ring it joins and the life the wearer leads:

• A discreet diamond band, a comfort-fit gold or platinum band with a flush-set natural diamond. A subtle option for a matching pair or a men’s wedding ring. Prodiam makes diamond-set jewellery; we do not supply plain metal-only bands.
• Diamond-set bands, a line of small calibrated diamonds set into the band, channel-set for the cleanest and most secure line, or claw and pave for more light. A row of light beside a solitaire, built to take daily wear.
• Half eternity, diamonds across the top half only, with plain metal under the finger. Easier to resize, kinder underneath, and the most practical diamond-set choice for an everyday wedding ring.
• Full eternity, diamonds the whole way round, an unbroken line of light from every angle. The classic anniversary or milestone piece, and a striking wedding ring in its own right.

The full detail on each construction, channel, shared-claw, U-set and pave, and on full versus half layouts, lives on the diamond wedding bands and eternity rings page.

Comfort fit and band width

Two things make a band comfortable on a hand that wears it around the clock: the profile and the width. A comfort-fit band is domed slightly on the inside so it glides over the knuckle and sits without a hard edge, which matters most on the wider, heavier bands men tend to choose.

Width is a balance, not a default: women’s bands are often 1.5 to 3 mm so they sit neatly against a slimmer engagement ring, while men’s bands are often 4 to 7 mm for presence on a larger hand. A wider band also wears warmer and feels tighter at the same finger size, which is one reason accurate sizing is worth getting right.

We profile every band to the hand it is going on, and on a his-and-hers pair we balance the two widths so neither overpowers the other.

Getting the size right

Because a wedding ring is worn every day, the finger size has to be correct rather than approximate. The reliable method is to be measured on a proper steel ring sizer, at the time of day and temperature you usually wear rings, since fingers swell in heat and shrink in cold, and to account for the width of the band, as a wider band feels tighter at the same size.

If you are commissioning remotely, we talk you through a simple measurement and build it in, and most bands can be resized later within reason. Our ring size guide sets out the method step by step, and if a ring ever needs adjusting down the line, our ring resizing and repair service handles it on the same bench that made it.

   Stones & quote

   For diamond-set bands we cut or match the diamonds on our Bedfordview bench within one colour and one clarity grade, and quote a firm ZAR figure, including VAT, against the stones, the metal and the making, before any work begins.

   Build & cast

   The band is built and cast in 18k white, yellow or rose gold, or platinum, sized to the finger and profiled to meet the engagement ring flush at the shoulder.

4. 04

   Set & finish

   Any diamonds are set at the bench, the seats cut by hand so the stones sit level and the line is even, then the band is hand-polished, brushed or matted to the finish you chose.

5. 05

   Hand-over

   Quality control under loupe and microscope, then presentation at Bedfordview by appointment, or insured overnight courier nationwide via Brink’s or G4S. GIA / EGL certification and a written insurance valuation on request where the band is diamond-set.
