Oval Engagement Rings · Bedfordview, Johannesburg
Oval engagement rings, cut and set in South Africa.
An oval is a brilliant in an elongated outline: it sparkles like a round but reads larger per carat and lengthens the finger, which is why it has become one of the most-requested engagement shapes.
Every Prodiam oval ring is made to order in our Bedfordview workshop, with the centre stone cut on our own bench or sourced to order and finished to keep the bowtie faint, then set as a solitaire or hidden halo in the metal you choose. Natural, GIA-certified diamonds, priced on application, with insured delivery anywhere in South Africa.

What an oval engagement ring costs
Almost all of the price is the centre stone. A one carat oval at H colour and SI1 clarity is about R47 100, and we can reach 363 of them right now. That is roughly R3 000 more than the same stone as a round brilliant, which is scarcity rather than quality: fewer are cut, so fewer are cut well. The setting is a much smaller number on top and we make it here.
| Centre stone | Typical | Entry | Available | |
|---|---|---|---|---|
| half carat | R12 600 | R10 500 | 36 629 | See ovals → |
| 1 carat | R60 200 | R41 900 | 28 838 | See ovals → |
| 1.5 carat | R152 100 | R101 700 | 12 496 | See ovals → |
| 2 carat | R329 200 | R195 500 | 6 378 | See ovals → |
| 3 carat | R849 000 | R568 000 | 2 213 | See ovals → |
Typical is H colour and SI1 clarity, the spec most people buy and the one that looks white and clean to the eye. Entry is the honest floor at that weight, usually a warmer colour. Both are stones we can put in front of you this week.

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.

Why an oval reads larger than its carat weight
An oval is a modified brilliant, the same family of light-returning facets as a round, drawn out into an elongated outline. That shape does two things at once: it presents a larger face-up area than a round of the same carat weight, so the stone looks bigger for the money, and its long axis draws the eye down the finger, which lengthens and slims the hand.
For a buyer who wants visible presence and brilliance together, the oval is often the most efficient way to get both.
The bowtie, and how a good cut beats it
Every elongated brilliant carries some bowtie, a darker band across the centre where the facets shadow the eye rather than returning light. It is not a flaw in the rough; it is a consequence of how the stone is cut, so the amount varies entirely with the cutter’s skill.
A well-cut oval keeps the bowtie faint and the stone bright corner to corner; a poorly cut one shows a heavy dark band that no setting can hide. Because we cut our own stones on our Bedfordview bench, we select and finish ovals to keep the bowtie minimal, and we always show you the stone face-up under daylight so you judge it with your own eyes.
Settings for an oval, solitaire and hidden halo
- Solitaire, the oval alone, usually in a four- or six-claw head, often with east-west or north-south orientation to taste. The clearest way to show the stone’s length.
- Hidden halo, a concealed pavé collar beneath the centre stone that adds light and lift without widening the outline, as on the ring shown above.
- Halo, a visible pavé frame that exaggerates the oval’s size and sparkle, matched to the centre on our bench.
- Pavé shoulders, small diamonds set along the band to carry light down the finger, in any of the above.
Ovals suit a slightly lower claw profile and benefit from claws that protect the two narrow ends, which take the most wear. We will talk you through the trade-offs against how the ring will be worn.
Choosing an oval: ratio, colour and clarity
| Choice | What we make to order |
|---|---|
| Length-to-width | ~1.30 (fuller) to ~1.50 (longer, more elegant) |
| Carat | From around 0.50 ct to 5 ct and above, to your budget and hand |
| Colour | D–F colourless, or G–I near-colourless; ovals can carry colour at the ends, so we check face-up |
| Clarity | An eye-clean VS–SI1, chosen so inclusions do not show at the table |
| Metal | 18k white, yellow or rose gold, or platinum |
| Certification | GIA / EGL certified; report supplied with the stone |
Pricing is on application, the stone drives the figure, and you receive a firm ZAR quote, VAT inclusive, before any work begins.

Oval engagement rings: common questions
Do oval diamonds look bigger than round diamonds of the same carat?
Generally, yes. An oval is an elongated shape, so for the same carat weight it presents a larger face-up area than a round, and the long axis draws the eye down the finger, which makes both the stone and the hand look longer and slimmer. It is one of the main reasons clients choose an oval, you tend to read more visible size per rand than you would from a round of equal weight.
What is the bowtie effect in an oval diamond?
The bowtie is a dark band that can appear across the centre of an oval (and other elongated brilliants), where the facets shadow the eye instead of returning light. Every oval has some bowtie; the question is how much. It is a function of cutting, not an inherent flaw, so a well-cut oval keeps it faint while a poorly cut one shows a heavy dark band.
Because we cut our own stones, we select and finish ovals to keep the bowtie minimal, and we show you the stone face-up so you can judge it yourself.
Are oval diamonds GIA certified and graded for cut?
Our oval diamonds are GIA or EGL certified and the report grades carat, colour and clarity in full. GIA does not, however, assign an overall cut grade to fancy shapes such as the oval, it grades only polish and symmetry, so for an oval the cutter’s skill, not a printed cut grade, is what governs brilliance and how faint the bowtie is. That is exactly the part a working cutting house controls.
What length-to-width ratio is best for an oval engagement ring?
It is a matter of taste, but most clients prefer a length-to-width ratio between about 1.30 and 1.50. Nearer 1.30 looks fuller and rounder; nearer 1.50 looks longer and more elegant. The report lists the measurements so you can work the ratio out, and we will show you stones at different ratios so you can see the difference on the hand before you choose.
Can you make an oval engagement ring if I am not in Johannesburg?
Yes, clients commission oval rings from Cape Town, Durban, Pretoria, Gqeberha and across South Africa. The stone and design conversation happens by video and WhatsApp, you approve the diamond and the setting, and the finished ring is delivered insured and overnight nationwide via Brink’s or G4S, with its certification and a written insurance valuation on request.
