Unusual Engagement Rings: Ideas Beyond the Solitaire
The solitaire engagement ring is the default, and for good reason: it is clean, timeless, and puts the diamond front and centre. But for buyers who want something with more character, more meaning, or simply a different kind of beauty, the alternatives are extensive and often more interesting than the conventional choice. The category of unusual engagement rings is broader and more varied than most people realise before they start looking.
TL;DR: Unusual engagement rings encompass a wide range: distinctive diamond shapes, coloured gemstone centres, multi-stone configurations, unconventional setting styles, and combinations of all of the above. The most unusual ring is usually the one made specifically for the wearer rather than adapted from a display case. Every style discussed here is available as a fully bespoke commission at À Vie Diamonds.
Unusual Diamond Shapes
Most people start thinking about unusual engagement rings at the level of diamond shape. Moving away from the round brilliant is the single most effective way to make an engagement ring feel distinctive without departing from a conventional diamond centre stone.
The marquise cut is one of the most striking fancy shapes and among the most underused. The elongated boat-shaped outline with pointed ends at both tips creates a dramatic silhouette that extends significantly along the finger. Marquise diamonds were a consistent choice from the 1960s through to the 1980s and have been relatively quiet since, which means a marquise ring currently reads as genuinely different rather than fashionably revived. See our full marquise engagement ring guide.
The Asscher cut is a square step cut with deeply cropped corners producing an octagonal outline. It was developed in 1902 by the Asscher Diamond Company in Amsterdam and became one of the defining jewellery shapes of the Art Deco period. The windmill pattern visible in the centre of a well-cut Asscher has a hypnotic quality that differentiates it sharply from any brilliant cut. It suits buyers drawn to architecture and geometric precision.
The rose cut is an historical cutting style in which the flat base and domed top produce a very different optical character from modern brilliant cuts. Rose cuts maximise surface area and give the stone a soft, antique glow rather than intense sparkle. They are not available through standard laboratory grading channels and tend to be found in vintage pieces or cut specifically for bespoke commissions. See our full rose cut diamond guide.
Coloured Gemstone Centres
Replacing the diamond entirely is a significant departure but one that an increasing number of buyers are making deliberately. The most practical choice is a sapphire, which at hardness 9 on the Mohs scale is the only coloured gemstone genuinely as suitable as diamond for daily wear in a ring. Blue sapphires are the most widely chosen coloured centre stone for engagement rings. Teal sapphires, with their distinctive blue-green dual tone, have become particularly popular in bespoke commissions over the past three to four years. Pink sapphires, rubies, and emeralds each have their own character and their own practical considerations — see our gemstone durability guide for how each performs in daily wear.
Choosing a coloured gemstone does not mean choosing an unconventional ring: coloured stone engagement rings have a history stretching back centuries and are a deeply traditional choice in many contexts. What they do is create a ring that is immediately recognisable as a specific, deliberate choice rather than the default.
Toi et Moi and Multi-Stone Designs
Multi-stone configurations, particularly toi et moi designs with two stones set side by side, are one of the fastest-growing categories in bespoke engagement ring commissions. The toi et moi is not new: Napoleon gave Joséphine one in 1796. Its current popularity reflects a broader move toward rings that tell a story and feel specific to the couple rather than generically beautiful.
Mixing stone types in a multi-stone ring, pairing an oval diamond with a teal sapphire or an emerald cut diamond with a round ruby, produces combinations that are inherently unique because no two stones of different types will have identical dimensions. Every toi et moi is bespoke by nature. See our detailed guide on toi et moi rings for more on this style.
Unconventional Settings
The setting can make a conventional stone unusual, or an unusual stone feel grounded. Some setting choices that produce genuinely distinctive rings:
A tension setting holds the stone suspended between the two ends of the band through compression rather than prongs or a bezel. The stone appears to float above the band with no visible support on the sides. The visual effect is striking. Tension settings require precise engineering and are more demanding to produce than conventional settings, but the result is one of the most architecturally interesting configurations in contemporary engagement ring design. See our full claw, pavé, and tension settings guide.
A bypass ring has a shank that crosses over itself, creating a dynamic, asymmetric silhouette. A single stone set at the crossing point, or two stones set at the two ends of the crossing shanks, produces a ring with movement and visual interest that a straight band cannot achieve.
An east-west setting rotates the stone 90 degrees so the long axis runs across the finger rather than up it. An east-west oval or marquise in a plain bezel reads as unexpectedly modern and is an effective way to make a recognisable shape feel entirely fresh.
Personalised Details
Some of the most unusual engagement rings are unusual because of specific personal details rather than dramatic shape or stone choices. A hidden stone set in the gallery beneath the centre stone, visible only when the ring is lifted. An engraved interior shank carrying a date or location. A specific combination of stones chosen because each one represents something meaningful. These details are invisible to a casual observer but carry weight for the person wearing the ring every day.
This kind of personalisation is exactly what bespoke production makes possible. A ring made to a specific brief can incorporate details that no off-the-shelf piece could offer.

Frequently Asked Questions
What makes an engagement ring unusual? Anything that departs from the default round brilliant solitaire in white metal: a distinctive diamond shape, a coloured gemstone centre, a multi-stone configuration, an unconventional setting style, or personalised details that make the piece specific to the wearer.
Are unusual engagement rings more expensive? Not necessarily. Many unusual choices, including fancy-cut diamonds and coloured gemstones, cost less per carat than round brilliants. The cost is determined by the stone quality, metal, and production complexity rather than by how conventional or unusual the design is.
Can I get an unusual engagement ring made on a moderate budget? Yes. A teal sapphire in a simple four-claw yellow gold solitaire, a marquise diamond in a plain platinum band, or an east-west oval bezel in 18ct white gold are all achievable at moderate budgets and produce rings that are immediately and obviously distinctive.
Is it risky to choose an unusual engagement ring as a surprise? It depends on how well you know the recipient's taste. The safest approach for a surprised proposal with an unusual ring is to have a strong sense of the specific aesthetic the wearer gravitates toward, or to frame the ring as a starting point and offer to adjust it afterward. Designing together removes the risk entirely.
What is the most unusual engagement ring style right now? Toi et moi designs combining a diamond and a coloured gemstone are the most rapidly growing unusual category. East-west settings and Asscher cuts are also growing consistently. The genuinely most unusual ring is one made specifically to a brief, because it cannot be replicated.
