Collection: Cushion Cut Diamond Engagement Rings

Solitaire suits the soft outline well, and a four-claw setting with rounded claws echoes the pillow shape rather than fighting it.

Halo is the most popular choice for a cushion, and there is a reason — a surround of small rounds against those curved sides looks quite romantic, and cushions with softer crushed-ice sparkle particularly benefit from the crisp contrast.

Three stone with half-moons or trapezoids either side flatters the curved outline, and rounds work equally well.

Side stones along the shoulders lift the ring and lead the eye into the centre stone, without competing with it.

Vintage-inspired settings — milgrain edges, filigree, a slightly raised gallery — suit cushions more than any other shape, given the cut descends from the old mine cut.

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.

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.

This is the part most buyers do not realise they are choosing, and it matters more than the outline. Cushions come in distinct faceting styles, and your certificate names which one you have.

Cushion Brilliant — the classic arrangement, with eight large pavilion facets. It produces broad, defined flashes of light: bigger, chunkier sparkle with clear dark and bright areas moving as the stone tilts. Often described as having more character or a bolder rhythm.

Cushion Modified Brilliant — an extra row of facets beneath the pavilion mains, breaking light into many smaller pieces. This is what people mean by crushed ice: a shimmering, glittery, all-over scintillation rather than distinct flashes. It reads as softer and more romantic, and it is very effective at disguising inclusions and body colour.

Antique or old mine cushions — cut before modern optics, with a high crown, small table and often an open culet. They give a warmer, candlelit glow rather than bright white return, and are prized by people who want something with genuine age.

None of these is better cut than the others. They are different optical effects, and the choice is entirely about which kind of sparkle you respond to. If you cannot decide from a description — most people cannot — that is exactly what an appointment is for.

Differently rather than less. A round brilliant is engineered for maximum white light return in a standardised pattern. A cushion trades some of that measured brilliance for fire — the coloured flashes you see when light splits into a spectrum. Cushions are known for it, particularly the antique and classic brilliant styles with their larger facets and higher crowns.

In candlelight or warm restaurant lighting, many people prefer a cushion. Under bright overhead light a round holds its own more consistently. Neither is objectively better; they perform differently in different rooms.

A square one carat cushion measures roughly 5.5 x 5.5mm, against about 6.4mm across for a round of the same weight. Cushions are often cut deeper than other shapes, carrying more of their weight below the girdle, so they can face up slightly smaller than the carat suggests. An elongated cushion at around 1.20 spreads further — closer to 6.5 x 5.4mm — and reads larger on the hand.

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. Cushions vary more than any other shape, so this is one where seeing several together is worth real money. 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. 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.
