What Is an Eternity Ring?
Last updated 28 October 2026
Quick answer
An eternity ring is a band set with a continuous row of matching stones, either all the way round (full eternity) or across the top (half eternity). It stands for love that lasts, and couples most often give one at an anniversary, the birth of a child or a vow renewal, or choose one as the wedding band. We make eternity bands to order in lab-grown diamond or moissanite, shaped in CAD to sit with your engagement ring.
What is an eternity ring?
A band set with a continuous row of matching stones. On a full eternity ring the stones go all the way round; on a half eternity ring they run across the top and the underside is plain metal. Most are set with round stones, and the band can be worn on its own, as a wedding band or beside an engagement ring.
What does an eternity ring mean?
Love that lasts. The unbroken line of stones stands for a commitment with no end, which is why the ring marks the moments a couple wants to remember.
When do you give an eternity ring?
Most often at a wedding anniversary, the birth of a child or a vow renewal, and some couples choose one as the wedding band from the start. There is no set anniversary for it: give it at whichever milestone matters to you.
Which finger does an eternity ring go on?
Usually the ring finger of the left hand, worn with the engagement ring and wedding band, or on its own on the right hand. Our guide to which hand and finger rings go on covers the order of the rings.
Full or half eternity: which should you choose?
Half eternity, for most people: it can usually be resized, the plain underside is more comfortable between your fingers, and it costs less. Choose full eternity if you want stones from every angle and you are sure of the size.
Full eternity
Stones all the way round, a 1.3mm band.
Half eternity
Stones across the top and a plain underside, a 2.4mm band.
| What changes | Full eternity | Half eternity |
|---|---|---|
| Stones | All the way round the band. | Across the top, with plain metal underneath. |
| When the ring turns | Stones still show. | The plain section can turn into view. |
| Comfort | Stones sit between your fingers. | Smooth metal sits between your fingers. |
| Resizing | Usually can’t be resized, so the size has to be right first. | Usually can, by a size or so, through the plain section. |
| Cost | More, because it takes about twice the stones. | Less, for the same stones and width. |
| Best for | Stones from every angle, when you are sure of the size. | Most people, especially as a wedding band worn every day. |
Can an eternity band be resized?
A half eternity band usually can, by a size or so, through its plain underside. A full eternity band usually can’t, because there is no plain metal to work on, so the size has to be right before it is made. Measure with our ring size chart or our guide to measuring your ring size, and our ring resizing guide covers which rings can be resized and what it usually costs.
Lab-grown diamond or moissanite for an eternity band?
Moissanite costs less across the many stones a band takes, so it suits a full eternity band where the budget matters. Lab-grown diamond matches a diamond engagement ring stone for stone. Our guide to moissanite vs diamond compares the two.
Can you make an eternity band to sit with my engagement ring?
Yes. Send us photos of your engagement ring from above and from the side, with its size, and we model the band in CAD against it, straight, curved or notched, even if another jeweller made your ring. We set lab-grown diamonds or moissanite in pavé, channel or bezel settings, in 14k or 18k gold or platinum, from a few stones to a full eternity band.
It takes about 4 to 6 weeks to make once you approve the design. See our custom wedding rings to start, and our guides to curved wedding bands and to bands for an oval or a pear engagement ring show how a band sits.
