Choosing an engagement ring is one of the most meaningful decisions you’ll make together. Whether you’re drawn to timeless elegance or something with a contemporary edge, exploring the popular engagement ring designs for 2026 will help you find a style that truly captures your relationship. This year’s trends offer a compelling mix of classic silhouettes and fresh interpretations, something for every couple, regardless of taste or budget.

At A Star Diamonds, our family-run team in Hatton Garden has spent years guiding couples through this exact journey. We’ve watched styles evolve and seen what resonates with people looking for that perfect symbol of commitment. In this guide, we’ll share ten standout ring designs currently trending across the UK, from elegant solitaires to romantic hidden halos, giving you the inspiration and knowledge to choose wisely or create a bespoke piece that’s entirely your own.

1. Bespoke engagement ring design with A Star Diamonds

When you want something truly unique, a bespoke engagement ring offers complete creative control. Instead of choosing from pre-made options, you work directly with experienced craftspeople to design every detail, from the diamond selection to the metal type, setting style, and band width. At A Star Diamonds, this personalised approach has become one of the most sought-after ways to create a meaningful symbol of commitment, and it consistently tops the list of popular engagement ring designs for couples who value individuality.

What it is

A bespoke ring starts with your vision. You’ll meet with our goldsmiths and designers in Hatton Garden to discuss your ideas, budget, and preferences. Our team then creates detailed sketches and CAD renderings so you can visualise the finished piece before any metal is cast. This collaborative process allows you to adjust proportions, try different stone shapes, and refine every element until the design perfectly captures your story. You’re not limited to existing templates or catalogue styles, which means your ring will be genuinely one-of-a-kind.

Why it’s popular in 2026

Couples today want authenticity and personal meaning woven into their jewellery. Mass-produced rings no longer appeal to those who see their engagement as unique, so they’re turning to bespoke design to create something that reflects their individual relationship and values. The rise of ethical sourcing has also increased demand for transparency, and a bespoke approach lets you choose exactly where your diamond comes from, whether natural or lab-grown.

"A bespoke ring allows you to express your unique love story in a way that ready-made jewellery simply cannot match."

Who it suits

This option works brilliantly if you have a clear vision or specific requirements that off-the-shelf rings don’t meet. You might want to incorporate a family heirloom stone, combine unusual design elements, or create something that fits an unconventional lifestyle. Couples who value craftsmanship and want to be involved in the creation process will find this approach deeply rewarding.

Key buying tips

Set a realistic budget before your first consultation, as bespoke doesn’t necessarily mean expensive but does require clarity about what you can invest. Allow six to eight weeks for the design and creation process, longer during busy periods. Ask to see examples of previous bespoke work and ensure your jeweller provides detailed drawings and costings before committing. Always confirm what’s included in aftercare, such as resizing and maintenance services.

2. Bezel set solitaire

A bezel set solitaire has become a standout choice among popular engagement ring designs for those who want a sleek, modern aesthetic combined with exceptional durability. This style features a single diamond encircled by a thin metal rim that holds the stone securely in place, creating a smooth, streamlined silhouette. The clean lines and protective setting appeal to people who lead active lives but refuse to compromise on elegance.

What it is

The bezel setting wraps a continuous metal band around the diamond’s girdle (widest part), holding it flush against the ring’s surface. Unlike prong settings where metal claws grip the stone from above, the bezel creates a smooth, uninterrupted border that protects the diamond’s edges. You can choose between a full bezel that circles the entire stone or a half bezel that covers just the top and bottom, allowing more light to enter from the sides.

Why it’s popular in 2026

People now prioritise practical luxury and want rings that withstand daily wear without constant worry. The bezel setting protects the diamond from chips and knocks, making it ideal for anyone with an active profession or hands-on hobbies. Its contemporary minimalism also aligns perfectly with current fashion trends that favour understated sophistication over excessive ornamentation.

"The bezel setting offers unmatched security for your diamond whilst maintaining a refined, modern appearance."

Who it suits

This design works brilliantly if you’re a healthcare professional, teacher, or athlete whose hands encounter frequent contact with surfaces. You’ll appreciate how the smooth setting won’t catch on gloves or fabrics. The style also suits those with a minimalist personal aesthetic who prefer clean, architectural lines over ornate details.

Key buying tips

Choose a bezel that’s thin enough to showcase your diamond but thick enough to provide proper security. Platinum offers the strongest hold, whilst yellow or rose gold creates warmer contrast against a white diamond. Ensure your jeweller leaves adequate space between the metal and stone for regular cleaning, and confirm they offer complimentary maintenance to keep the bezel tight over time.

3. Hidden halo solitaire

The hidden halo solitaire has emerged as one of the most elegant popular engagement ring designs for couples who want a touch of sparkle without overwhelming the centre stone. This sophisticated style features a delicate circle of small diamonds set beneath the main diamond, visible only from the side or when you move your hand. The subtle shimmer adds dimension and light whilst maintaining the clean, classic silhouette of a traditional solitaire.

What it is

A hidden halo places a ring of small pavé or micro-pavé diamonds directly under the centre stone’s girdle, nestled into the setting where the head meets the shank. You’ll notice the extra brilliance when light catches these stones from certain angles, but the design maintains the understated elegance of a single-stone ring when viewed from above. The halo typically uses diamonds ranging from 0.8mm to 1.5mm in diameter.

Why it’s popular in 2026

This style perfectly balances traditional sensibilities with contemporary refinement. You get the added sparkle and visual interest without the overt embellishment of a full halo, which appeals to those who prefer subtlety. The hidden diamonds also create the illusion of a slightly larger centre stone whilst keeping the overall aesthetic clean and timeless.

"A hidden halo adds brilliance where you least expect it, creating delightful moments of discovery."

Who it suits

This design works beautifully if you appreciate classic solitaires but want something with a subtle twist. You’ll love how it adds personality without drawing attention away from your diamond’s natural beauty.

Key buying tips

Ensure the hidden halo uses high-quality stones that match your centre diamond’s colour grade. Request that your jeweller sets the halo flush against the basket to prevent snagging, and confirm the prongs securing the small diamonds are reinforced for durability.

4. Oval cut solitaire with a tapered band

The oval cut solitaire paired with a tapered band has secured its place among the most sought-after popular engagement ring designs for 2026. This graceful combination elongates the finger whilst maintaining the brilliance of a classic round diamond, making it perfect for those who want sophistication with a contemporary twist. The tapered band draws attention directly to the centre stone, creating an elegant transition from finger to diamond.

What it is

An oval cut diamond features 58 facets arranged in an elongated shape that maximises sparkle and fire. When set as a solitaire on a tapered band, the shank gradually narrows as it approaches the setting, creating visual interest without competing with the stone. You’ll find the band typically starts at 2.5mm to 3mm wide at the back and tapers to 1.5mm where it meets the head.

Why it’s popular in 2026

Oval diamonds offer excellent value for carat weight because their elongated shape covers more surface area than round cuts of the same weight. The tapered band creates a sleek, modern silhouette that complements the stone’s elegant proportions whilst remaining comfortable for daily wear. This combination suits current preferences for designs that feel both timeless and distinctly contemporary.

"The oval’s elongated shape paired with a tapered band creates an unmatched sense of grace and proportion."

Who it suits

This design works beautifully if you have shorter fingers or prefer rings that create a lengthening effect. You’ll appreciate how the tapered band prevents the ring from feeling too chunky whilst the oval cut offers maximum visual impact.

Key buying tips

Choose an oval with a length-to-width ratio between 1.35 and 1.50 for the most pleasing proportions. Ensure your jeweller uses a secure four or six-prong setting to protect the pointed ends, and confirm the band tapers gradually rather than abruptly to maintain structural integrity.

5. Emerald cut Art Deco style setting

The emerald cut diamond set in an Art Deco inspired design brings geometric sophistication to the roster of popular engagement ring designs for 2026. This pairing celebrates the glamour of the 1920s and 1930s, combining the step-cut facets of an emerald diamond with architectural metalwork that emphasises symmetry and clean lines. You’ll find intricate millgrain edging, channel-set baguettes, and geometric patterns that transform a simple engagement ring into a statement piece.

What it is

An emerald cut features rectangular or square step-cut facets that create a hall-of-mirrors effect rather than the sparkle of brilliant-cut stones. When placed in an Art Deco setting, jewellers surround it with geometric metalwork, often incorporating tapered baguette side stones, milgrain detailing, and symmetrical patterns inspired by 1920s architecture. The setting typically uses platinum or white gold to honour the period’s preference for these metals.

Why it’s popular in 2026

This style appeals to those who appreciate vintage aesthetics with historical significance. The emerald cut’s sophisticated clarity showcases diamond quality rather than hiding inclusions beneath sparkle, which resonates with buyers seeking authenticity. Art Deco’s structured elegance perfectly complements modern minimalist trends whilst adding distinctive character.

"The emerald cut’s transparent beauty paired with Art Deco geometry creates a ring that commands attention through refined sophistication rather than excessive flash."

Who it suits

You’ll love this design if you appreciate architectural details and vintage fashion. It suits confident individuals who want a ring that sparks conversation.

Key buying tips

Select an emerald cut with VS2 clarity or higher since step facets reveal inclusions easily. Ensure the Art Deco detailing uses quality craftsmanship with secure stone settings, and confirm your jeweller offers proper maintenance for intricate metalwork.

6. Pear shape with a halo

The pear-shaped diamond encircled by a halo of smaller stones has become one of the most romantic popular engagement ring designs for 2026. This distinctive teardrop silhouette combines the brilliance of a round cut with the elegance of a marquise, whilst the surrounding diamonds amplify both size and sparkle. You’ll find this design particularly captivating when the halo follows the pear’s unique contours, creating a seamless flow from pointed tip to rounded base.

What it is

A pear-shaped diamond features 58 facets arranged in a teardrop form with one pointed end and one rounded end. The halo setting surrounds this centre stone with a border of small round or pavé diamonds, typically measuring 1mm to 1.5mm each. Jewellers carefully shape the halo to mirror the pear’s outline, ensuring the pointed tip receives adequate protection whilst the rounded base maintains visual balance.

Why it’s popular in 2026

This design delivers maximum visual impact because the halo adds approximately half a carat’s worth of perceived size to your centre stone. The pear shape itself offers excellent finger coverage, whilst the surrounding diamonds catch light from every angle, creating constant sparkle that suits both formal occasions and daily wear.

"The halo transforms a pear diamond into a radiant focal point that commands attention through sheer brilliance."

Who it suits

You’ll love this design if you want distinctive elegance without straying too far from traditional styles. It suits those with longer fingers who can showcase the pear’s full length.

Key buying tips

Ensure your jeweller uses a V-prong or bezel tip to protect the pointed end from chips. Choose a pear with excellent symmetry and confirm the halo sits close enough to enhance without overwhelming the centre stone’s natural beauty.

7. Three-stone trilogy with fancy side stones

The three-stone trilogy featuring fancy cut side stones represents one of the most symbolic popular engagement ring designs for 2026. This meaningful arrangement places a centre diamond between two complementary stones, traditionally representing your past, present, and future together. When you choose fancy shapes like trapezoids, baguettes, or half-moons for the side stones, you create striking geometric contrast that elevates the design beyond conventional settings.

What it is

A trilogy setting positions three diamonds across the ring’s width, with the centre stone slightly larger than its flanking companions. Fancy side stones deviate from standard rounds or baguettes, using distinctive shapes such as shield cuts, bullet cuts, or cadillac shapes that create architectural interest. Your jeweller sets these stones closely together, often using shared prongs to maintain a seamless appearance whilst maximising light performance.

Why it’s popular in 2026

This design offers rich symbolism that resonates with couples seeking meaning beyond aesthetics. The fancy side stones add personality whilst the three-stone structure provides excellent finger coverage and perceived value, allowing you to distribute your budget strategically across multiple diamonds.

"Three stones create a narrative of your relationship whilst fancy cuts add distinctive character that sets your ring apart."

Who it suits

You’ll appreciate this design if you want storytelling symbolism combined with visual impact. It suits those who prefer balanced compositions over single-stone dominance.

Key buying tips

Ensure your side stones complement rather than compete with your centre diamond. Choose fancy cuts that harmonise with your main stone’s shape, and confirm all three diamonds receive secure settings that prevent loosening during wear.

8. Toi et moi two-stone ring

The toi et moi (French for "you and me") two-stone ring has captured hearts as one of the most romantic popular engagement ring designs for 2026. This intimate style places two diamonds of equal or complementary size side by side, symbolising two souls coming together as one. You’ll find this design particularly meaningful because each stone can represent you and your partner, creating a visual metaphor for partnership and unity.

What it is

A toi et moi setting features two stones positioned closely together on a single band, typically with their tips touching or nearly meeting. Jewellers often use different diamond shapes to create contrast, such as pear and round, oval and emerald, or marquise and cushion combinations. The stones sit at a slight angle to follow the finger’s natural curve whilst maintaining balance and symmetry.

Why it’s popular in 2026

This design offers deeply personal symbolism that resonates with couples seeking meaningful representations of their relationship. You can choose stones with different characteristics that reflect your individual personalities, making each ring genuinely unique.

"Two stones together create a powerful symbol of partnership, where distinct individuals unite whilst maintaining their unique beauty."

Who it suits

You’ll love this design if you value romantic symbolism and want something distinctly different from traditional solitaires. It suits couples who embrace their individuality within the relationship.

Key buying tips

Ensure both stones receive secure settings with adequate prongs or bezels. Choose complementary shapes that create visual harmony, and confirm the setting sits low enough for comfortable daily wear without catching on fabrics.

9. Cluster engagement ring

The cluster engagement ring has re-emerged as one of the most distinctive popular engagement ring designs for 2026, offering exceptional sparkle through multiple diamonds arranged in a cohesive pattern. This vintage-inspired style groups several smaller stones together to create the visual impact of a larger centre diamond whilst maintaining affordability and unique character. You’ll find clusters particularly appealing if you want maximum brilliance without the premium price tag of a single large stone.

What it is

A cluster ring arranges multiple diamonds in a geometric or floral pattern, typically featuring a slightly larger centre stone surrounded by smaller accent diamonds. Jewellers set these stones closely together using shared prongs or pavé techniques, creating a unified sparkling surface that maximises light reflection. You’ll find clusters ranging from seven stones in a flower pattern to elaborate arrangements featuring dozens of diamonds in symmetrical designs.

Why it’s popular in 2026

This style delivers exceptional value because several smaller diamonds cost significantly less than one large stone of equivalent total carat weight. The vintage aesthetic appeals to those seeking character and history, whilst the brilliant sparkle satisfies modern preferences for eye-catching designs.

"Cluster settings transform modest budgets into spectacular displays of brilliance through clever diamond arrangement."

Who it suits

You’ll love this design if you appreciate vintage jewellery and want distinctive character. It suits those seeking maximum sparkle within a realistic budget.

Key buying tips

Ensure all diamonds receive secure settings with reinforced prongs to prevent stone loss. Choose a cluster with consistent diamond quality throughout, and confirm your jeweller offers complimentary maintenance since multiple stones require regular checking.

10. Unisex signet style engagement ring

The unisex signet style engagement ring breaks traditional gender norms to become one of the most progressive popular engagement ring designs for 2026. This bold approach reimagines the classic signet ring’s substantial profile and flat surface, replacing ornate diamond settings with streamlined designs that suit any gender. You’ll find this style particularly appealing if you value equality and want jewellery that transcends conventional expectations whilst maintaining sophisticated presence.

What it is

A signet style engagement ring features a wide, flat surface set atop a solid band, traditionally used for engraving family crests or monograms. Modern interpretations incorporate flush-set diamonds or gemstones directly into the signet’s face, creating a smooth, tactile surface that maintains the style’s characteristic weight and presence. The band typically measures 6mm to 12mm wide, offering substantial coverage that feels secure and permanent.

Why it’s popular in 2026

This design reflects evolving attitudes towards gender and jewellery, appealing to couples who reject traditional engagement ring conventions. The substantial construction suits active lifestyles whilst the minimalist aesthetic aligns with contemporary fashion preferences for understated luxury and practical elegance.

"Signet styles offer a refreshing alternative for couples seeking engagement rings that celebrate partnership without conforming to outdated gender expectations."

Who it suits

You’ll love this design if you prefer bold, architectural jewellery over delicate settings. It suits those with confident personal style who want substantial rings that feel significant.

Key buying tips

Ensure the signet face sits low enough for comfortable daily wear without catching. Choose quality metals like platinum or 18ct gold for durability, and confirm flush-set stones receive proper depth to prevent loosening during wear.
