Solitaire engagement rings,made in Australia.

Every year since the mid-1880s, the single-stone solitaire has been the most popular engagement ring design in the world. It has outlasted the three-stone, the pavé, the halo, the hidden halo, the toi et moi, and every other setting fashion that has come and gone. Every one of those styles has had its moment. The solitaire has had 140 years.

The reason is simple. A solitaire is a proposal reduced to its essential geometry: one person, one diamond, one commitment. Nothing distracts from the stone. Nothing distracts from the meaning. In a category where design trends turn over every decade, that clarity keeps working.

If you're drawn to a solitaire, you're not choosing minimalism because it's fashionable. You're choosing the one setting that has never gone out of style. Three of the top five best-selling engagement rings at our four showrooms every year are solitaires, and that hasn't changed since we opened in 2006.

The modern engagement ring solitaire has a specific inventor and a specific date. Charles Lewis Tiffany introduced the Tiffany Setting in 1886, and it changed engagement ring design permanently.

Before 1886, diamond engagement rings sat in bezel or flush settings. The stones were held tight against the band, and the metal that surrounded them absorbed light before it could enter the diamond. Rings were beautiful but visually flat.

Tiffany's innovation was to lift the diamond above the band on six thin platinum claws. Suddenly, light could enter the stone from every angle, refract through the pavilion, and return to the eye. The diamond didn't just sit on the ring, it floated. Sparkle went up by an order of magnitude.

Every solitaire made anywhere in the world since 1886 traces its DNA back to the Tiffany Setting. The six-prong classic solitaire we make today at our Sydney workshop is a direct descendant of that 1886 invention. The four-prong variant came later as a Deco-era simplification. Both are Tiffany's legacy.

The single most-asked question at our four showrooms about solitaire settings, and the one no competitor page explains. Here's the honest answer.

4-claw solitaire. Shows the maximum amount of diamond. Easier to clean. Modern, minimalist look. Sits slightly higher on the finger. Best for cushion, princess, radiant, and asscher cuts, where corner claws stabilise sharp geometry. Slight trade-off: if a single prong fails, only three hold the stone. In practice this is exceptionally rare on 18ct or platinum settings that are inspected annually.

6-claw solitaire. The Tiffany classic since 1886. Rounds the diamond visually, six symmetric claws create the illusion of a perfect circle even on slightly imperfect stones. If one prong fails, five hold. Best for round brilliant and oval cuts. Sits slightly lower than 4-claw because the claws distribute weight around the diamond's circumference. Our most-ordered solitaire configuration.

8-claw solitaire. A speciality setting for pear, marquise, elongated cushion, and heirloom stones with unusual proportions. The extra claws stabilise the pointed or elongated ends and permit thinner individual claws (each holds less of the diamond, so you see more stone). Rare in the mass market. We build these in our Sydney workshop on request.

Which to choose: if you don't already know, choose 6-claw. It's the Tiffany classic, the most secure, and it flatters the widest range of centre-stone shapes.

Prong count is one variable. Setting construction is the other, and no ranking competitor explains it. Four constructions dominate solitaire design.

Classic solitaire. The pared-back reference implementation. Straight band, prongs rise vertically from the top of the band, no metalwork underneath the diamond. Cleanest silhouette. Highest diamond-to-metal ratio. Our most-ordered construction.

Cathedral solitaire. The band arches upward on both sides to meet the setting, forming a small vaulted structure under the diamond (hence "cathedral"). Adds visual height to the ring, makes a small diamond look larger, and creates a more sculptural profile from the side view. Slightly harder to nest with a wedding band flush against the solitaire, a curved contour wedder usually solves this.

Trellis solitaire. The prongs cross under the diamond in a woven X-pattern rather than rising straight up. Creates a distinctive side-view detail and often permits fewer visible claws on the top. Modern, understated, distinctly Australian in origin (the trellis solitaire is more common in AU and UK than in US-market rings).

Basket solitaire. A small horizontal band of metal sits underneath the diamond, forming a basket that supports the pavilion. Adds security for very large stones (2ct+). Very slightly reduces light return from the pavilion because the basket blocks some under-lighting. Best for buyers who prioritise security over maximum sparkle.

A hidden option worth naming: hidden accents inside the gallery. Some of our solitaires include a small halo of pavé diamonds set on the gallery walls under the centre stone, invisible from above, glinting from the side. Technically still a solitaire from the front-on view. If you love the solitaire silhouette but want a small hidden detail, this is the setting to ask us about.

Every shape works as a solitaire. Some sing.

Round brilliant. The reference implementation. 6-claw or 4-claw both work. Maximum light return of any cut. If you can't decide, this is the safe classic. About 45% of the solitaires we make.

Oval. The ideal solitaire shape for finger elongation. A well-cut oval reads about 15% larger face-up than a round of the same carat weight. Best in 6-claw or 8-claw settings. About 25% of the solitaires we make and rising every year.

Cushion cut. Vintage-romantic character in a modern-friendly silhouette. Best in 4-claw or corner-claw 8-claw settings. Chunky-facet and crushed-ice variants both work as solitaires.

Emerald cut. The most demanding solitaire shape. Step cuts have no brilliance-hiding faceting, every inclusion is visible. Solitaire emerald requires higher clarity (VS1 or better) than a haloed emerald would. When it works, it's the most sophisticated of all solitaires. 4-claw with corner claws.

Princess cut. Sharp geometric solitaire. Requires 4-claw corner setting to protect the fragile 90-degree corners. Modern, distinctive.

Pear. Best in 5-claw or 6-claw with a v-tip prong protecting the point. Distinctly bridal.

Radiant, asscher, marquise, heart. All work as solitaires with the right prong configuration. Ask us at your consultation.

Nobody in the AU search results explains this properly. Here's the pairing matrix.

Round solitaire + straight plain band. The reference pairing. Sits flush. Timeless. About half our solitaire buyers choose this pairing.

Round solitaire + curved contour band. The contour band curves around the base of the solitaire's setting to nest flush. Adds visual sophistication without competing with the centre stone.

Oval solitaire + deep-curve contour band. Ovals sit low and long, so a deeper contour reads better than a straight band. Straight bands leave a visible gap between band and setting on ovals.

Pear solitaire + v-shaped contour band. The v-notch nests the pear's point.

Emerald and asscher solitaire + straight plain band. Step cuts sit flat; a straight band matches the geometry.

Cushion solitaire + straight or gently curved band. Either works. Curved reads slightly more romantic; straight reads slightly more modern.

Bespoke wedder. Any solitaire can be paired with a bespoke matching wedder cut and shaped in our Sydney workshop. Add three to four weeks to your wedder timeline if you want a perfect flush fit.

Every ranking retailer sells both. Nobody publishes a straight comparison. Here's ours.

Choose a solitaire if: you love clean minimalism, the recipient prefers understated elegance, you want the setting to be timeless in fifty years, or you plan to invest more in the centre diamond (a solitaire lets the money go into carat weight and cut quality rather than accent stones).

Choose a halo if: you want a smaller centre diamond to look larger (a well-set halo can make a 0.75ct centre read like a 1.25ct), you love the extra sparkle, or the recipient prefers a more decorative ring style.

Choose a hidden halo if: you want a solitaire silhouette from the front-on view but a small secret detail visible from the side.

The re-set factor. A solitaire is the easiest engagement ring to re-set with a different centre stone in the future (say, a larger diamond for a milestone anniversary). Halos are much harder to re-work without redesigning the ring.

No hedging. Real Australian dollar ranges for a solitaire from our Sydney workshop, current as of July 2026.

One of the requests we receive most often at our Sydney workshop.

If you have a diamond from a family piece, a grandmother's ring, an inherited pendant, a wedding stone from a previous marriage, a solitaire is the easiest and most respectful setting to re-set it into. The single-stone geometry works with any shape, any carat weight, and any grading pedigree.

Our re-setting service. Bring the stone (or the whole piece) to any of our four showrooms. Our master jeweller will assess the diamond's dimensions, condition, and any pre-existing certification. We'll show you the four constructions from Section 04 with the actual stone loose in each setting style, and you'll choose the one that best honours the piece and suits daily wear. Turnaround is four to six weeks.

If the stone has no certificate, we can send it to GIA (natural) or IGI (lab-grown) for independent grading before setting, worth doing if the diamond is 0.75ct or larger, as certification adds meaningful resale and insurance value.

Some heirloom stones aren't structurally sound enough to re-set, a diamond with a chipped girdle or a large surface-reaching inclusion may need to be re-cut before it can safely be worn daily. Our master jeweller will tell you honestly what's possible before you commit.

Because a solitaire has more exposed diamond than any other setting, it's slightly more prone to knock damage, but also easier to clean and maintain than any other engagement ring style.

What to know.

If you wear a solitaire daily, expect very fine surface scratches on the metal after 6-12 months. This is normal on any daily-worn ring. A professional polish at any of our four showrooms every 12-18 months restores the finish to as-new.

If you knock the ring hard on a surface, look at the prongs from above under a lamp, if any claw looks bent, tilted, or misaligned, come in immediately. A bent prong is a five-minute fix in our Sydney workshop. An unsecured stone that falls out is a $10,000 problem.

Take the ring off for the gym, contact sports, gardening, and heavy manual work. Diamonds are the hardest natural material but can chip on impact against another diamond or against a metal surface.

Cleaning at home: warm water, drop of mild dish soap, soft toothbrush, pat dry. Weekly. Focus on the underside of the diamond where skin oil and hand cream collect and dull the light return.

Professional maintenance: every 12-18 months at any of our four showrooms. Included in our lifetime warranty at no cost. We ultrasonic-clean, re-tip any worn prongs, polish the band, and re-inspect the setting.

The final decision every solitaire buyer faces.

Natural or lab-grown. Chemically, optically, and physically identical. GIA grades natural centre diamonds; IGI grades lab-grown. Both use the 4Cs scale. Both grade to the same standards. Lab-grown solitaires cost 40-50% less than natural solitaires at the same specification.

Where to spend it. On a solitaire more than any other setting, the single best return on money spent is on cut quality. A 0.90ct excellent-cut solitaire outperforms a 1.00ct good-cut solitaire on every visual metric, bigger face-up appearance, more sparkle, whiter light return. Do not sacrifice cut for carat.

Where to save it. Colour and clarity have diminishing returns above a certain grade. G-H colour is indistinguishable from D-F colour to the naked eye in a solitaire under normal lighting. VS2 clarity is indistinguishable from VVS1 clarity to the naked eye. Buy for the eye, not for the certificate.

Our house recommendation for a 1ct solitaire buyer under budget pressure: natural, F-G colour, VS2 clarity, GIA excellent-cut, 18ct white gold classic 6-claw. Or the lab-grown equivalent at 45% off. Both configurations perform beautifully and photograph beautifully.
