Collection: Round Diamond Engagement Rings

Solitaire first, because nothing has outlasted it. A single round on a plain band is the reference point every other engagement ring is measured against, and a well-cut stone needs nothing else. Four claws show more of the diamond and give a cleaner, more modern line; six claws hold it more securely and read as slightly more traditional. Both are correct — it is a question of look and, if you are hard on your hands, a little practicality.

Halo frames the stone with a surround of smaller rounds and makes the centre read noticeably larger, which is useful if you are weighing carat against budget.

Three stone suits a round particularly well, with a matched pair either side or tapered baguettes for something more streamlined.

Side stones and pavé put diamonds along the shoulders and lift the whole ring without drawing attention from the centre.

All made to order in our own workshop, built around your stone.

Every ring is made to order, usually in around 2–3 weeks once your diamond has been chosen. We'll give you a clear, realistic timeframe for your design when you enquire.

Four claws show a little more of the diamond and give a more modern look. Six claws hold the diamond more securely and give a softer, rounder look. Daniel can show you both so you can see the difference.

Yes. Every design is a starting point. The metal, band, claws and setting can all be adjusted, or we can make your own design from scratch.

A well-proportioned one carat round brilliant measures roughly 6.4–6.5mm across. Diameter is what the eye reads as size, not carat weight, so two one-carat stones can look noticeably different depending on how they are cut. A stone carrying extra weight in the pavilion weighs the same and looks smaller.

Round brilliant is the only shape GIA assigns a formal cut grade to, on a five-tier scale from Excellent to Poor. Excellent and Very Good both perform well in the hand. Cut is what actually produces sparkle, so it is the one of the 4Cs we would suggest you compromise on last — a poorly cut D Flawless will look duller than a well-cut G VS2, and cost considerably more.

Tell us the number you have in mind and what matters most to you, and we will show you the best stones we hold at that level. We are a diamond merchant, not a retail jeweller — we do not charge retail prices, and we source natural certified diamonds to suit your budget rather than steering you toward whatever is in the display case. Diamond Imports is a foundation member of the Diamond Dealers Club of Australia, and you will deal directly with Daniel throughout.

No. Every diamond we sell is a natural diamond, and we've never dealt in lab-grown, simulants or treated stones.

A lab-grown stone is a manufactured product. It's grown in a reactor over a few weeks, then mass produced in unlimited quantities in any size or grade. That's the fundamental difference: a natural diamond took billions of years to form and exists in finite supply, while a laboratory-grown one is a commodity with no ceiling on production. It shows in the pricing — as capacity has scaled, lab-grown prices have fallen steeply and continue to fall, and there is no established secondary market for them.

What you're buying with a natural diamond is scarcity and origin. Rare, and natural. It's why we've never sold anything else. Read our full comparison of natural and lab-grown diamonds.

Our diamonds are independently certified, most commonly by GIA, with others graded by DCLA or HRD. The certificate is issued by the laboratory, not by us, and it accompanies the stone when it ships.

Yes. We are in Sydney's CBD and we see clients by appointment, so you can view stones side by side and compare them in person before deciding.

Just ask us. Finding a particular stone is a large part of what we do, and there's no obligation when you enquire. We'll do our best to source the finest quality natural diamond for you.

Our list is smaller than you'll see on some sites, and that's deliberate. Every diamond here is one we've looked at properly before listing it. Many diamond websites show tens or hundreds of thousands of stones drawn from shared trade lists — diamonds held elsewhere that the seller hasn't seen and won't see unless you order one. It looks like more choice, but nobody has assessed the individual stone, and two diamonds with the same details on paper can look quite different.

So if what you want isn't here, tell us what you're after and what you'd like to spend. We'll look for it, check anything we find ourselves, and only show you stones we'd be happy to recommend. If we can't find the right thing at your budget, we'll say so and talk through the options — sometimes a small change in colour, clarity or size makes all the difference.

Either way, you'll only ever be offered a diamond that we have complete confidence in recommending to you, and it will not just be based on the cheapest price.

Yes. Most clients select the diamond first and then the setting — either one of our existing designs or a fully custom piece made to your description or an image. Everything is handmade by our own jewellers.

Yes. We have many loyal customers all over Australia, and we're able to consult by phone and share photos and videos whenever possible.

Distance is not the obstacle people expect. We'll guide you through the options and select the finest quality diamonds and gemstones for you, so you can make an informed decision from wherever you are. The same applies to custom made engagement rings and jewellery — we'll talk you through it and keep you across it as it's made.

We deliver fully insured anywhere in Australia — every capital city, and regional and rural addresses just the same.

If you are able to come in, we'd always rather show you the stones in person — and if you're travelling to Sydney, appointments can be arranged on weekends.
