Diamond Eternity Rings

A diamond eternity ring is given to mark a moment that already has a name — a significant anniversary, the birth of a child, a milestone birthday — and worn for decades afterward alongside an engagement ring and wedding band. This collection of 148 rings spans half-set and full-set designs, round brilliant and fancy-cut diamonds, slim channel profiles and bold semi-bezel statements, all made to order in our Hatton Garden workshop. Every ring is available in gold or platinum, hallmarked at the London Assay Office, and delivered with complimentary insured UK shipping.

The collection is built around lab-grown diamonds certified by GIA, IGI or HRD — the same grading laboratories that certify natural stones, assessing colour, clarity, cut and carat weight by the same criteria. A pavé-set round such as the Ulla Eternity Lab Diamond Ring 1ct at £1,434 and a channel-set baguette design like the Kelly Baguette Eternity Lab Diamond Ring at £2,325 illustrate the range — both share the same certification standard and the same workshop process, differing only in cut character and setting geometry.

Every ring in this collection is set with certified diamonds, coloured diamonds or gemstones at the client's choice. The process runs from CAD design through a silver or wax sample review at the Hatton Garden workshop, then casting, setting, finishing and hallmarking before insured UK delivery. Lead time is 7–14 working days from order confirmation. Free resizing for life and a lifetime warranty against manufacturing defects are included on every order.

When is an eternity ring given?

Tradition associates the eternity ring with the first significant anniversary or the birth of a first child — a moment of continuation rather than beginning. The symbolism of an unbroken or near-unbroken line of stones around the band reflects a relationship already established and likely to continue, which is why eternity rings are almost always given after the wedding rather than as part of the engagement or ceremony itself.

In practice, the occasions have broadened. Milestone birthdays, decade anniversaries, the birth of a second or third child, and major personal achievements are all common triggers. The ring's visual character — continuous, restrained, designed to stack — makes it a natural addition to a hand already wearing an engagement ring and wedding band. Some clients commission an eternity ring to replace a wedding band that no longer fits comfortably, or to upgrade an earlier wedding band as a tenth or twentieth anniversary gift. There is no single correct occasion; the more useful question is whether the ring will be worn as part of a stack or on its own.

Half-set versus full-set: which is right?

The most consequential decision in choosing an eternity ring is whether the stones run halfway around the band or all the way around. A half-set — diamonds across the top hemisphere, plain metal underneath — is more comfortable for everyday wear, can be resized at any point, and represents the majority of eternity rings worn in the UK. A full-set encircles the entire band in stones and cannot be resized without rebuilding the setting, because cutting into the band breaks the continuous line.

For a ring that will be worn daily alongside a wedding band and engagement ring, half-set is the more practical specification. The plain underside also means the ring sits flatter on the finger without rotation. Full-set is the right choice when the wearer's finger size is stable, the ring will occasionally be worn alone, and the visual effect of a continuous line of stones around the full circumference matters. The Semi-Bezel Round Eternity Lab Diamond Ring 2.5ct and the Semi-Bezel Emerald Cut Eternity Lab Diamond Ring 3ct are both full-set designs; if either appeals, confirm your finger size before ordering.

Diamond cut and setting style

Round brilliants dominate the category because they return the most light per carat and work with any metal or skin tone. Across the top face of a half-set band, the visual effect is a continuous bright line — the standard eternity-ring reading. Fancy cuts change the character meaningfully. Baguettes, as in the Tabitha Channel Set Baguette Eternity Lab Diamond Ring and the Kelly Baguette Eternity Lab Diamond Ring, produce a linear, architectural finish with broad flat facets and less flash than a round. Emerald cuts, as in the Nathalie Emerald Cut Eternity Lab Diamond Ring 2ct, produce a similar effect with wider stones and more visible inclusions — clarity grade matters more with step cuts.

Setting style also governs the ring's visual weight. A classic claw or prong setting maximises light entering each stone but leaves the metal of the band exposed between stones. A channel setting, as in the Tabitha Channel Set Eternity Lab Diamond Ring 0.33ct, runs the stones between two rails of metal, producing a cleaner line with no individual claws to catch. A semi-bezel wraps each stone in a partial rim of metal — more protective than a claw, more open than a full bezel, and the setting style that most readily suits oval and round stones on a band worn daily.

Matching an eternity ring to an existing engagement ring

An eternity ring worn as part of a three-ring stack needs to sit flush against both the wedding band and the engagement ring. Width is the primary consideration: an eternity band that is significantly wider than the wedding band will dominate the stack rather than complement it. Most clients in this collection choose an eternity band between 1.8mm and 3mm wide to sit harmoniously alongside a standard 2–2.5mm wedding band.

Metal matching is conventional but not obligatory. A platinum engagement ring pairs naturally with a platinum eternity band; mixed-metal stacks — yellow gold wedding band, white gold or platinum eternity ring — are equally common and provide a deliberate contrast. Where the engagement ring has a distinctive shoulder profile or a halo setting, a slimmer, plainer eternity band tends to read better than a bold statement piece. The Nathalie Oval Eternity Lab Diamond Ring and the Olivetta Eternity Lab Diamond Ring both sit at a width that stacks well against most standard engagement ring profiles.

How much should an eternity ring cost in the UK?

Price is determined by total diamond weight, the cut (fancy cuts such as emerald and oval carry a higher per-carat premium than rounds), the metal, and whether the ring is half-set or full-set. In this collection, half-set lab-grown diamond eternity rings begin around £1,000 — the Tabitha Channel Set Eternity Lab Diamond Ring 0.33ct at £1,015 is the accessible entry point. The £1,400–£2,000 range covers 1ct total weight in round or oval cuts, represented by rings such as the Ulla Eternity Lab Diamond Ring 1ct at £1,434 and the Valencia Eternity Lab Diamond Ring 1.5ct at £1,959. Full-set and higher-carat designs such as the Semi-Bezel Oval Eternity Lab Diamond Ring 3ct at £2,876 sit at the top of the range.

Lab-grown diamonds carry the same grading criteria as natural stones but cost considerably less per carat, which means a higher total weight is achievable at any given budget.

Made to order at President Jewellers

Every eternity ring in this collection is made to order in our Hatton Garden workshop. Lead time is 7–14 working days from order confirmation — simpler channel-set and half-set designs at the faster end, full-set and bespoke configurations closer to fourteen days. The process begins with a CAD rendering of your chosen design, followed by a silver or wax sample review at our Hatton Garden showroom where width, profile and stone spacing can be assessed before any metalwork begins.

Casting, setting and polishing take place in our UK workshop; every ring is hallmarked at the London Assay Office before delivery. Insured UK delivery is complimentary on every order, with no minimum spend. Free resizing for life and a lifetime warranty against manufacturing defects are included as standard. If you have an existing engagement ring and want to discuss which eternity ring will sit most naturally alongside it, we recommend booking a Hatton Garden consultation before committing to a specific design.

Frequently asked questions

When should a woman get an eternity ring?

There is no fixed convention. The most common occasions in the UK are a significant wedding anniversary — the first, fifth, tenth or twenty-fifth — and the birth of a first or subsequent child. Milestone birthdays are increasingly common triggers. The ring does not need to follow a rule; the relevant question is whether the occasion feels like one that warrants a piece of jewellery intended to be worn indefinitely alongside an engagement ring and wedding band. Many clients commission an eternity ring five to fifteen years into a marriage, once the significance of the relationship has its own history to mark.

How much should I pay for an eternity ring?

In this collection, half-set lab-grown diamond eternity rings begin around £1,000 and rise to approximately £3,000 for full-set designs with 2.5ct–3ct total weight. The UK average spend on an engagement ring is £2,247 (Bridebook, 2026); eternity rings are typically purchased at a similar or slightly lower value. The most useful budget framework is to decide on total diamond weight first, then choose between half-set and full-set — that single decision changes the price by 30–50% for the same carat weight, because full-set rings require roughly twice the number of stones.

Should eternity rings have diamonds?

Diamonds are the most common choice because their hardness makes them well suited to a ring worn daily for decades, and their optical character produces the characteristic bright line across the band. However, sapphires, rubies, emeralds and other gemstones are all available in this collection. A sapphire eternity ring, for example, offers a distinct colour register and comparable durability. The right choice depends on how the ring will be worn and what the recipient prefers — there is no technical reason to restrict the choice to diamonds.

What is the difference between a half-set and a full-set eternity ring?

A half-set eternity ring has diamonds set across the top hemisphere of the band, with a plain metal underside. A full-set encircles the entire band continuously. Half-set rings can be resized; full-set rings cannot without rebuilding the stone setting, because resizing requires cutting through the band. For most clients who will wear the ring daily over many years, half-set is the more practical choice. Full-set rings are suited to clients whose finger size is stable and who want the visual effect of an unbroken continuous line of stones from every angle.

How long does an eternity ring take to make?

7–14 working days from order confirmation. Straightforward half-set channel designs are typically ready at the faster end of that range; full-set, bespoke or fancy-cut designs sit closer to 14 working days. The process involves a CAD design stage and a silver or wax sample review at our Hatton Garden workshop before casting begins. Insured UK delivery is included and tracked through to receipt. If your order is time-sensitive — for an anniversary or birthday with a fixed date — contact us before placing the order and we will confirm whether the schedule is achievable.

Are the diamonds in these rings independently certified?

Yes. Every diamond in this collection is certified by GIA, IGI or HRD — the three principal independent grading laboratories. The certificate accompanies the ring on delivery and records the stone's colour, clarity, cut and carat weight. Lab-grown diamonds receive the same grading assessment as natural stones; the certificate indicates which type the stone is. We do not offer uncertified diamonds in this collection. If you want to review a specific certificate before ordering, contact us with the product and specification you have in mind.
