Why Full Eternity Bands Canβt Be Resized
A design decision made once, that you live with for forty years.

Short answer
Resizing works by cutting the shank at the back, adding or removing metal, and soldering it closed. A full eternity band has stones all the way round, so there is no plain metal to cut and nowhere to apply heat without risking the settings. It usually has to be remade rather than resized. A half or three-quarter eternity band leaves bare metal at the back and resizes normally β which is why it is the safer choice if your size might ever change.
People buy full eternity bands because they are beautiful from every angle, which they are. What almost nobody is told at the point of sale is that they are effectively a fixed-size object, and fingers are not fixed-size things.
How resizing actually works
To make a ring smaller: cut the shank at the back, remove a measured segment, bring the ends together, solder, clean up and repolish. To make it larger: cut, insert a matching piece of the same metal and karat, solder, finish.
Both require two things. A section of plain metal to cut and rejoin. And the ability to apply localised heat at that point without it reaching set stones.
A full eternity band offers neither. Every millimetre of the circumference carries stones, so there is no bare section, and heat applied anywhere travels through the whole band into every setting.
| Band type | Plain metal at the back? | Resizing |
|---|---|---|
| Plain band | All of it | Straightforward, several sizes either way |
| Half eternity (stones across the top) | Yes, the whole back | Straightforward |
| Three-quarter eternity | A short section | Possible, limited range |
| Full eternity, prong or shared prong | None | Generally remake only |
| Full eternity, channel set | None | Remake β channel walls cannot be reworked partially |
Why βjust remove a stoneβ does not work
It sounds like an obvious solution: take out one stone, close the gap, done. In practice the stones in an eternity band are spaced to an exact spacing that runs the full circumference. Remove one and every remaining stone is now in the wrong place relative to the others.
On a shared-prong band the problem is worse, because adjacent stones sit in prongs they share. Removing one leaves prongs holding nothing on one side, which then have to be rebuilt.
And you cannot generally go up in size at all this way, since adding a stone means lengthening the band, which means new metal in the middle of a stone run.
The part people underestimate: fingers change, permanently. Not just the half-size that comes and goes with heat and salt. Finger size shifts over decades with weight, with pregnancy, with joint changes in later life, and with a lot of medications. A band bought at 28 and worn daily until 70 will almost certainly need adjusting at some point. If that band is a full eternity, the answer at that point is not a resize β it is a new ring, or wearing it on a chain. That is the real cost, and it lands decades after the purchase.
Full eternity still makes sense in some cases
None of this means do not buy one. It means buy one knowingly.
- Your size has been stable for years and you are not planning pregnancy.
- It is an anniversary or milestone band rather than the ring you never remove.
- You wear it occasionally rather than daily, so slight looseness is not a risk.
- You simply want it, having read the above. That is a legitimate answer β it is genuinely the most beautiful version of the design.
The alternatives, ranked by how much you give up
- Three-quarter eternity. Visually almost identical when worn β the bare section sits under the finger where nobody sees it. Resizable within a limited range. For most people this is the right answer and it is rarely offered.
- Half eternity. Stones across the visible top half only. Fully resizable, cheaper, and no visual difference from above.
- Full eternity, but in a size you are confident about, with the acceptance that it may become a chain pendant or a right-hand ring later.
What to ask before you order
Ask directly: can this design be resized, and by how many sizes in each direction? A workshop knows this immediately for anything it builds. An answer of βyes, most rings can be resizedβ is a non-answer, and on a full eternity band it is wrong.
Ask it before the piece is cast, not after it arrives. On a made-to-order band the size is set at the wax stage, and switching from full to three-quarter eternity at that point costs nothing.

Frequently asked questions
Can a full eternity ring be resized?
Generally no. Resizing requires cutting a section of plain metal at the back and soldering it, and a full eternity band has stones all the way round, so there is no bare section and no safe place to apply heat. In most cases the band has to be remade at the new size rather than altered.
What is a three-quarter eternity band?
A band with stones around about three quarters of its circumference, leaving a short plain section at the very back. Worn on the hand it looks essentially identical to a full eternity, because the bare part sits under the finger β but it can be resized within a limited range. It is often the best compromise and is rarely offered by default.
Why can't a jeweller just remove one stone to size it down?
Because the stones are set to an exact spacing that runs the full circumference. Removing one leaves every remaining stone misaligned relative to the others, and on shared-prong bands it leaves prongs holding nothing. Sizing up is harder still, since it would mean inserting new metal into the middle of a continuous stone run.
Should I buy a full eternity band as a wedding ring?
Only if you accept that it may need remaking rather than resizing at some point. Finger size changes permanently over decades with weight, pregnancy, joint changes and some medications, and a ring worn daily for forty years will very likely need adjusting. For a ring you never take off, a half or three-quarter eternity is the more practical choice.
Ask us about three-quarter eternity.
It looks the same on the hand and it can still be resized. We will build either, but we will tell you which one we would choose.
