The 2026 Engagement Ring Trend Report

The 2026 Engagement Ring Trend Report: Eight Defining Styles From the Oak & Murphy Collection

The shapes, settings, and silhouettes dominating fine jewelry — and the women who inspired every one of them.

There is a particular kind of power that lives in the engagement ring. It is a piece anticipated and cherished far long before it is chosen, imagined long before a question is ever asked, and studied — on strangers' hands, on Instagram feeds, in the glow of a magazine — with the focused attention of a collector. This year, that imagination has never been richer. After half a decade of the minimalist solitaire reigning supreme, 2026 arrives with something to say: that elegance, individuality, and architectural precision are not competing ideas. They are the same idea, expressed through extraordinary diamond shapes and the settings brave enough to honor them.

At Oak & Murphy, the engagement ring collection reads less like a catalog and more like a manifesto. Every style is intentional. Every cut was selected because it belongs to a specific woman — one who knows the difference between timeless and tired, between sparkle and presence. What follows is a guide to eight trend categories reshaping the bridal landscape in 2026, as told through the lens of the Oak & Murphy engagement ring collection.

01. The Oval Obsession — The Era's Reigning Shape

The oval diamond did not rise to cultural dominance by accident. Its elongated form has a quiet genius: it flatters nearly every hand, appears larger than a round diamond of equivalent carat weight, and catches light with a brilliance that seems almost to breathe. It has become the engagement ring shape that women design themselves — shopping alongside their partners, referencing saved screenshots, building entire Pinterest boards simply titled "yes."

Hailey Bieber's six-carat oval on a delicate gold band remains one of the most-referenced engagement rings in the history of social media. Kourtney Kardashian said yes to a breathtaking oval with a pavé diamond band and hidden halo shimmer beneath the stone. Lady Gaga confirmed her own engagement with a handcrafted eight-carat oval set in 18K yellow gold. And when Georgina Rodríguez stepped into the spotlight wearing what experts estimated to be a 30-carat oval diamond on a diamond-studded band, the internet collectively stopped breathing. Then Simu Liu proposed to Allison Hsu in Paris with a ten-carat oval set on a simple gold band. The shape, it seems, is not a trend. It is a permanent fixture of the fine jewelry conversation — and in 2026, it is only getting more interesting.

What is particularly compelling this year is not simply the shape, but how designers are framing it. At Oak & Murphy, the oval appears across six distinct architectural approaches — each one a different conversation with the same stone. The V-shaped shank version lifts the stone with dramatic precision. The wrap solitaire embraces it. The hidden halo options surround it in secret brilliance. And the five-stone configuration stacks it into a continuous arc of light across the finger.

02. The Marquise Moment — A Royal Revival

If 2024 was the year the oval consolidated its reign, 2025 was the year the marquise staged the most anticipated comeback in modern fine jewelry. The announcement came with the kind of cultural velocity that only Selena Gomez — the most-followed woman on Instagram — can generate. When Benny Blanco proposed with a marquise diamond on a yellow gold pavé band, the shape immediately entered the bridal conversation with a force that surprised even industry veterans. Jewelry experts reported a surge in marquise inquiries that continues well into 2026. National Jeweler documented the cultural ripple in real time.

The shape's history gives it authority that trends cannot manufacture. Dating to the 18th-century French court — where King Louis XV reportedly commissioned a diamond to echo the lips of his mistress, the Marquise de Pompadour — the cut has always carried an air of aristocratic confidence. Victoria Beckham wore one from David Beckham. Jackie Kennedy accepted one from Aristotle Onassis. Catherine Zeta-Jones said yes to one from Michael Douglas. The marquise has consistently attracted women of a particular self-assurance, and in 2026, that energy is everywhere.

Its optical appeal is no accident either. The elongated, pointed silhouette creates the impression of considerably greater size per carat than almost any other shape, and it lengthens the finger with an elegance closer to couture than casual. As Jillian Sassone, founder and creative director of Marrow Fine, noted: it is a shape traditionally associated with royalty. A marquise diamond does not simply sit on the hand. It presides.

Oak & Murphy has embraced this shape across four distinct settings — from a clean minimalist solitaire to an elevated cathedral architecture with a hidden halo, to the ultimate statement of a horizontal three-stone setting.

03. The Secret Shimmer — The Hidden Halo Effect

There are engagement ring details that announce themselves from across a room. And then there is the hidden halo — tucked beneath the center stone, invisible unless the light catches it from exactly the right angle, a private constellation of small diamonds that elevates the brilliance of the entire ring without altering its silhouette. It is the fine jewelry equivalent of a perfectly tailored lining: something personal, known only to those who look closely.

This intimacy is precisely what has made it one of the most consistently sought-after features among women who have done their research. Lady Gaga's oval engagement ring — confirmed during the Paris Olympics in 2024 — features a hidden halo beneath the center stone. Bridgerton actress Phoebe Dynevor's oval in 18K yellow gold carries the same detail. Kourtney Kardashian's jaw-dropping oval from Travis Barker was designed with a hidden pavé halo for that exact effect: brilliant when you know it's there, invisible when you don't.

What these women share is a preference for depth over display — a ring that rewards attention rather than demanding it. The hidden halo is a choice made for oneself, not for the room.

In the Oak & Murphy collection, the hidden halo appears across four distinct diamond shapes: on the oval, the marquise, the emerald cut, and the radiant. The Radiant Diamond Engagement Ring with Hidden Halo and Diamond Band is particularly compelling — the radiant cut's hybrid brilliance paired with a fully diamond-set band creates a ring that catches light from every direction, at every hour.

04. The Chevron Effect — V-Shaped Shanks and Architectural Elegance

One of the quietest and most consequential shifts in engagement ring design over the past year is the migration away from straight, uniform bands toward the V-shaped shank — a design in which the band tapers to a distinct point beneath the center stone, creating a chevron silhouette that is simultaneously architectural and deeply flattering.

The effect on the hand is considerable. The converging lines draw the eye upward toward the diamond, framing it with a kind of intentionality that a straight solitaire band cannot replicate. The point beneath the stone creates negative space — a compositional pause — that makes the center diamond appear more dramatic and more elevated than its dimensions alone would suggest. It is the kind of detail that separates a ring from a fine jewelry piece to a design object.

In 2025, independent designers including Grace Lee and Vanessa Fernandez received significant editorial recognition for their explorations of sculptural band geometry — work that placed the setting itself, not just the stone, at the center of the ring's visual identity. Zendaya's engagement at the 2025 Golden Globes, with its architectural east-west setting, was perhaps the most talked-about example of this tendency toward geometric intentionality in bridal jewelry. The V-shank is a direct expression of that same philosophy.

At Oak & Murphy, the V-shaped shank appears in both oval and pear configurations — two stones whose elongated profiles are particularly amplified by the drama of the chevron beneath them.

05. The Romantic Teardrop — Pear Diamonds and the New Feminine

The pear diamond has a particular quality that no other shape quite replicates: it is simultaneously delicate and dramatic, romantic and decisive. Its rounded base tapers to a single pointed end, creating a silhouette that — when worn with the point toward the fingertip — produces one of the most elongating effects of any diamond shape. Like the marquise, it borrows brilliance from the round cut. Like the oval, it flatters. But the pear brings something distinctly its own: the impression of softness, of a stone that has arrived at its shape by nature rather than by machine.

Margot Robbie — whose taste in fashion, film, and beauty has made her one of the most-referenced women in contemporary culture — revealed her pear-shaped diamond engagement ring set in yellow gold with a half-pavé band by posting a single, wordless photograph on Instagram. The ring, with its warm gold setting and teardrop center stone, struck exactly the right note: romantic but not fussy, personal but universally beautiful. In 2025, jewelry experts consistently noted the pear's resurgence across solitaire, halo, and sculptural settings, calling it the shape that offers a balance of feminine elegance and bold individuality that no other cut currently matches.

The Oak & Murphy collection includes two distinct pear expressions. The first is a clean, architecturally elevated V-shank solitaire that uses geometric precision to amplify the drama of the teardrop shape. The second — the Pear Diamond Engagement Ring with Botanical Diamond Accents — takes the pear into more lyrical territory, pairing the elongated stone with organic, nature-inspired diamond details that make the ring feel as much like a wearable sculpture as a bridal piece.

06. The Legacy Setting — Multi-Stone Romance for the Modern Era

The three-stone engagement ring has always carried meaning. The classic symbolism — past, present, future — is one of the few pieces of jewelry mythology that has actually endured, passing from generation to generation without losing its resonance. What has changed in 2026 is not what the ring represents, but the extraordinary range of ways it can now say it.

The traditional trio of round brilliants in graduated sizes has given way to inventive combinations that feel entirely contemporary. As The Knot's engagement ring trend report noted, designer Stephanie Gottlieb has called three-stone rings the perfect balance of impact and tradition — a design that allows couples to make a bold statement while maintaining a connection to a more classical aesthetic. Multi-stone rings made up over half of all engagement rings chosen in 2024, and their share of the conversation is only growing.

The Oak & Murphy Marquise Three-Stone Diamond Engagement Ring represents the category at its most compelling. Three marquise diamonds arranged in a horizontal constellation — their pointed ends creating a continuous, scalloped line across the finger — is an entirely different proposition from the conventional round brilliant trilogy. It is more directional, more editorial, and more unexpected.

The Oval Diamond Five-Stone Engagement Ring operates differently — stacking brilliance across the finger in a way that creates the visual impact of a full eternity band within the proportions of a single statement ring. Both pieces transform the legacy concept into something genuinely new.

07. The Botanical Edit — Fine Jewelry Meets the Garden

There is a corner of the fine jewelry world that resists geometry. That builds its beauty not from precision and angles but from the organic irregularity of things that grow. Floral motifs, vine-like details, diamond accents placed as though scattered by nature rather than arranged by a craftsman. This aesthetic — which has deep roots in Art Nouveau and the nature-obsessed jewelry of the early 20th century — is experiencing a quiet but considered revival in 2026.

Independent designers Grace Lee and Leen Heyne have both spoken about their desire to create rings that feel as though they emerged from the natural world: stones chosen for character rather than perfection, settings that support a stone rather than confine it. The botanical trend in engagement rings is an extension of this sensibility — an acknowledgment that the most extraordinary fine jewelry does not impose itself on nature but borrows from it.

Within the Oak & Murphy collection, the Pear Diamond Engagement Ring with Botanical Diamond Accents in 14K Gold gives this aesthetic its most direct expression. The pear diamond — a shape already associated with organic softness — is accompanied by delicate diamond accents arranged in a floral, nature-inspired motif that frames the center stone with the lightness of something in bloom. The result is a ring that feels grown rather than manufactured, with the kind of intimate detail that rewards close attention and improves with every wearing.

This is a ring for the woman who has strong opinions about gardens, about art, about the way beautiful things are always slightly imperfect.

08. The Emerald Edit — The Step-Cut's Return to the Spotlight

There is a reason the emerald cut has maintained its following through every decade, every trend cycle, every wave of competing shapes. It does not try to dazzle you. Where round brilliant diamonds radiate sparkle from every facet, the emerald cut — with its long, parallel step-cut facets and rectangular silhouette — creates something closer to a hall of mirrors: a cool, glassy depth that draws the eye inward rather than scattering it outward.

It is a shape for women who are not interested in performing. It defined the Art Deco era. It has been worn by Amal Clooney, Grace Kelly, and an entire lineage of women who understood that restraint is its own kind of power. In 2025, influencer and tennis star Paige Lorenze announced her engagement with an emerald-cut diamond ring — a choice that confirmed the step-cut's enduring, cross-generational appeal to women who know exactly what they want and do not need the room's permission.

The Oak & Murphy Emerald Diamond Solitaire Engagement Ring with Hidden Halo in 14K Gold brings a modern counterpoint to the shape's classical restraint. The cool geometry of the emerald cut is met by the warmth of a hidden halo beneath the stone — a detail that adds brilliance and dimension without disturbing the elongated, architectural profile above. The result is a ring that honors tradition while quietly insisting on something more.

A Final Note: The Classic That Never Leaves

Amid the shape revivals and setting innovations of 2026, the round brilliant diamond remains what it has always been: the standard against which all other engagement rings are measured. Its 58 perfectly calculated facets were engineered for maximum light return, and no other shape achieves that level of pure, uninterrupted sparkle. Emma Roberts' announcement of her engagement to Cody John with a round brilliant solitaire in a substantial yellow gold band was a quiet reminder that the most enduring ring choice is often also the most personal. Oak & Murphy carries the Round Diamond Engagement Ring in 14K Gold for exactly that reason: because some preferences are not trends. They are convictions.

Shop the Full Collection

The best engagement ring is almost never the one chosen in haste or chosen to impress. It is chosen for the woman who will wear it — for the way a shape suits her hand, for the way a metal reads against her skin, for the way it makes her feel when she looks down at it in the morning light.

At Oak & Murphy, every piece in the collection was designed with this in mind. The collection spans shapes — oval, marquise, pear, emerald, radiant, round — alongside settings including solitaire, hidden halo, cathedral, wrap, and multi-stone, all crafted in 14K yellow and white gold. Because no two proposals are alike, and no two women should be wearing the same ring.
