Gemstone Eternity Rings

A gemstone eternity ring moves beyond the all-diamond tradition and introduces colour, texture or contrast into a band that runs stones continuously or across the upper half of the finger. This collection of 29 rings spans emerald-cut lab diamonds and natural diamonds, black diamonds, lab-grown emeralds, and mixed-metal Celtic knotwork — each made to order in our Hatton Garden workshop and hallmarked at the London Assay Office. Whether the ring marks a significant anniversary, the birth of a child, or simply a milestone that deserves something more personal than a colourless band, the 29 pieces here cover the range. For context on how these bands sit within a wider ring stack, see the full eternity ring collection and the wedding ring collection.

The range divides into two broad groups. The first uses coloured or distinctive stones as the principal feature — rings such as the Eternity Lab Emerald and Diamond Eternity Ring (£1,959), which alternates lab-grown emeralds with diamonds for a green-and-white contrast, or the Glacier Eternity Black Diamond 6mm Wedding Ring (£2,417), a wider band in which black diamonds lend an architectural opacity rather than sparkle. The second group uses emerald-cut lab or natural diamonds in a continuous channel, offering a step-cut optical character quite different from round brilliants. Every ring in both groups is made from certified diamonds or certified coloured gemstones — there are no uncertified stones in this collection.

All orders include complimentary insured UK delivery, free resizing for life, and a lifetime warranty against manufacturing defects. Loose stones purchased separately are dispatched within 5–7 working days; set into a ring, the combined schedule is 7–14 working days from order confirmation.

What is a gemstone eternity ring?

An eternity ring is a band set with stones running continuously around the full circumference, or across the top half in a half-eternity configuration. A gemstone eternity ring introduces material other than a standard colourless diamond — this can mean a coloured stone such as an emerald or sapphire, a diamond in an unusual colour such as black or champagne, an unusual cut such as the step-cut emerald, or a combination of two materials in alternating sequence.

The distinction matters practically. A full-set band cannot be resized without dismantling the setting; a half-set can usually be adjusted by one to two sizes. Coloured stones, particularly softer gemstones on the Mohs scale, require attention to hardness — emeralds, for example, are harder than most everyday materials but more brittle than diamonds and benefit from a bezel or channel setting over prong setting in a ring worn daily. The pieces in this collection use channel and rub-over settings for precisely this reason: stone security over the long term.

What stone is right for an eternity ring?

The choice of stone is partly a question of durability and partly a question of meaning. Diamonds — including black or treated diamonds — are the most practical choice for a band worn every day alongside an engagement ring; they score 10 on the Mohs scale and hold their surface over decades of contact with other metal and hard surfaces. Coloured gemstones introduce a personal or symbolic dimension: emerald is traditionally associated with growth and renewal; sapphire with loyalty; ruby with commitment. The eternity ring collection also includes diamond options for those who want to compare.

Lab-grown stones — available across this collection in both emerald and diamond — are chemically and optically identical to their natural equivalents and certified by the same laboratories: GIA, IGI, or HRD. They allow higher carat weights at a lower price point, which matters on an eternity ring because the total stone weight across the band accumulates quickly. A 2ct total-weight emerald-cut lab diamond band, such as the Emerald Eternity Lab Diamond Ring 2ct at £2,194, would cost considerably more in natural diamonds of comparable grade.

Half-set versus full-set in a gemstone eternity ring

A full-set band encircles the entire finger with a continuous line of stones. Visually it reads as more intense from every angle, and the symbolism of an unbroken circle carries weight for many clients. The practical constraint is that it cannot be resized — the continuous setting has no plain section of metal to cut and rejoin without breaking the sequence. A full-set ring should be bought once finger size is stable.

A half-set band runs stones across the upper hemisphere — roughly 180 degrees — and leaves the underside plain. It can be resized by one or two sizes as needed, and it is generally more comfortable for those who work with their hands, because the inner surface remains smooth. For a ring that will sit alongside an engagement ring and a wedding band in a three-piece stack, a half-set profile also provides a flatter seat against the adjacent rings. The wider bands in this collection — the Glacier Eternity Black Diamond 6mm and the Mixed Metal Celtic Eternity Knot 6mm — are full-set by design; the slimmer emerald-cut bands are available in both configurations.

When is a gemstone eternity ring given?

There is no strict rule, but convention in the UK places the eternity ring at one of three moments: the first significant wedding anniversary, a milestone anniversary such as the tenth or twenty-fifth, or the birth of a first or subsequent child. Some couples exchange an eternity ring at the wedding itself, in place of or alongside a separate wedding band. The timing matters less than the intention — an eternity ring is a second or third piece added to a ring finger already carrying an engagement ring, and it draws meaning from that accumulation.

Because gemstone eternity rings introduce colour, they tend to be chosen at the anniversary or birth moment rather than at the wedding — the coloured stone marks a chapter that came after the engagement, and the visual contrast against a white-metal or diamond engagement ring signals that distinction. A ring like the Eternity Lab Emerald and Diamond Eternity Ring, alternating green and white, reads differently from the engagement ring and is clearly a separate, later piece. That narrative distinction is, for many clients, the point.

How much does a gemstone eternity ring cost in the UK?

In this collection, prices begin at £1,369 for the Mixed Metal Celtic Eternity Knot 6mm and rise to £25,926 for the Emerald Eternity Diamond Ring 8ct in natural diamonds. The mid-range — lab-grown stones in 18ct gold or platinum at 2ct–4ct total weight — sits between roughly £2,200 and £5,000. For comparison, the UK average spend on an engagement ring is £2,247 (Bridebook, 2026), so an eternity ring in this range represents a comparable investment.

The biggest single variable is whether you choose lab-grown or natural stones. At 3ct total weight, the lab-grown emerald-cut diamond band — the Emerald Eternity Lab Diamond Ring 3ct at £3,559 — costs approximately one-seventh of the equivalent natural diamond version. Both carry independent certification from GIA, IGI, or HRD; the optical and chemical properties are the same. The decision is a personal and financial one rather than a quality one.

Made to order at President Jewellers

Every ring in this collection is made to order in our Hatton Garden workshop. Lead time is 7–14 working days from order confirmation — simpler bands sit at the lower end of that range; wider pavé or complex mixed-metal designs at the higher end. The process begins with a CAD rendering of the design, followed by a silver or wax sample available for review at our Hatton Garden showroom before any metalwork begins. Casting, stone setting, finishing and polishing are completed in the UK; every ring is then hallmarked at the London Assay Office and dispatched by insured, tracked UK delivery.

Metals available across this collection include 9ct, 14ct and 18ct gold in white, yellow or rose, and 950 platinum. White metals — particularly platinum — suit the cooler tones of black or colourless diamonds; yellow and rose gold complement the warmer palette of green, blue or ruby-coloured stones. If you already hold a loose certified stone and wish to have it set into one of these bands, contact us before ordering — the stone is delivered separately within 5–7 working days, and the ring follows the standard 7–14 working day schedule.

Frequently asked questions

When should a woman get an eternity ring?

Convention in the UK places it at the first anniversary, a milestone anniversary such as the tenth, or the birth of a child. These are the three moments where the ring's symbolism — a continuous circle added to the engagement ring already on the finger — carries the most weight. That said, there is no obligation. Some couples exchange an eternity ring at the wedding; others wait until the second or third child. The timing is personal; the ring marks whatever occasion the couple decides it marks.

What stone should an eternity ring be?

Diamonds remain the most practical choice for daily wear, as they are the hardest natural material and hold their surface indefinitely. For a ring that introduces colour, emeralds and sapphires are the most established options — emeralds for growth and renewal, sapphires for loyalty and depth. Harder stones (Mohs 8 and above) are better suited to an eternity band than softer stones such as opals or pearls, which would wear against the adjacent engagement ring. Whatever stone is chosen, ensure it is independently certified and set in a channel or rub-over setting for security.

How much should I pay for an eternity ring?

In this collection, gemstone eternity rings range from £1,369 to over £25,000. Most clients spending on a post-wedding eternity ring in the UK are in the £1,500–£5,000 range for a lab-grown stone band, or £3,500–£10,000 for natural certified stones at comparable carat weights. The main levers are total stone weight, metal choice, and lab-grown versus natural origin. Lab-grown stones allow you to buy a higher total carat weight for the same budget without any optical compromise — the stones are certified by the same laboratories and look the same to the eye.

What are the four rings a woman should have?

The four-ring convention is: an engagement ring, a wedding band, an eternity ring, and a right-hand ring worn independently of the bridal set. This is a retail framing rather than a formal tradition, but it reflects how many clients in the UK build a ring wardrobe over time. The eternity ring is the third piece in that sequence, added to the finger that already carries the engagement ring and wedding band. A gemstone eternity ring introduces colour and distinction — it reads as a separate chapter rather than a continuation of the original set.

How long does a gemstone eternity ring take to make?

Every ring in this collection is made to order. Lead time is 7–14 working days from order confirmation. Simpler half-set bands in a standard metal and size are typically completed closer to 7 working days; wider or more intricate designs — mixed-metal work, full-set bands, complex channel settings — tend toward 14. A CAD rendering is shared before metalwork begins, and a sample can be reviewed at our Hatton Garden workshop. Insured UK delivery is included on every order and is tracked through to receipt.

Can a gemstone eternity ring be resized?

Half-set bands — stones across the upper hemisphere only — can generally be resized by one to two sizes without disturbing the setting. Full-set bands, where stones run around the entire circumference, cannot be resized without rebuilding the setting, because there is no plain section of metal to cut and rejoin. This applies to all full-set rings regardless of where they are purchased. We offer free resizing for life on rings that are eligible for adjustment; for full-set bands, we recommend confirming your finger size carefully before ordering, and a visit to our Hatton Garden showroom is always available for fitting.
