Can Your Ring Be Resized?

A ring that doesn't fit is one of the most common reasons anything crosses our bench. Sometimes it's an inherited piece that fits nobody currently alive. Sometimes it's a proposal ring sized by an educated guess. Sometimes it's a wedding band that fit perfectly in 2014.

The short answer: most rings can be resized, usually by a size or two in either direction, and it's routine work. But a meaningful number genuinely can't be — and when a ring can't be sized, the reason is almost always one of two things: how it was built, or what it's made of.

We're Chapel Hills Jewelry, family-owned on Freeport Road in the Aspinwall area of Pittsburgh since 1989. Sizing, repairs and restoration are done here, on our own bench, by our master benchman — so what follows is what he'd actually tell you if you set the ring on the counter.

What resizing actually involves

It helps to know what's happening, because it explains every limitation that follows.

To size a ring down, a section of the shank — the band at the bottom of the finger — is cut out, the two ends are brought together and soldered, and the join is filed, polished and finished until it's invisible. To size a ring up, the shank is cut and a matching piece of metal is added in, then soldered and finished the same way.

Two things follow from that. First, the work happens at the bottom of the ring, so anything built into the bottom of the ring is in the way. Second, it involves heat — which matters enormously for certain stones.

How far a ring can go

A size or two in either direction is comfortable territory for most plain or partially set rings. Beyond that, things change: sizing up substantially thins the shank and can distort a round ring into a slight oval, and sizing down significantly can crowd the setting and change how the ring sits.

Larger jumps aren't automatically impossible — but they stop being a simple sizing job and become a shank replacement or a rebuild, which is a different conversation about a different piece of work. If you're moving three or four sizes, expect that conversation.

Rings that are difficult or impossible to size

Eternity bands

The most common "no" we give. An eternity band has stones set continuously around the entire circumference — there's no plain metal at the bottom to cut into. Removing metal means removing stones, and the remaining stones no longer sit at the right spacing.

This is why eternity bands are often bought in the exact final size and why a half-eternity band — stones across the top, plain metal underneath — is the more practical choice for anyone whose size might change. If you already own a full eternity band that doesn't fit, it usually needs to be remade rather than sized.

Channel-set and full pavé bands

Same problem, to a lesser degree. If small stones run most of the way around in a channel or a pavé field, the metal that would need to be cut is structural — it's holding stones in place. Sometimes there's enough plain shank at the bottom to work with. Sometimes there isn't. This one genuinely requires a look.

Tension settings

A tension setting holds the center stone by spring pressure between two ends of the band — the metal itself is the setting. Altering the shank changes that pressure, which is the one thing holding the stone in. These are generally not sizable in the ordinary way, and shouldn't be attempted as though they were.

Tungsten, titanium, ceramic and stainless steel

These cannot be resized at all — not by us, not by anyone. They're not a matter of difficulty; the materials can't be cut and soldered the way precious metals can. Tungsten carbide in particular is extremely hard and brittle rather than malleable.

If a band in one of these materials doesn't fit, it gets replaced, not altered. This is worth knowing before buying one — it's the most common unpleasant surprise in men's wedding bands. Gold and platinum bands, by contrast, are sizable, which is a genuine practical argument for them in a ring meant to be worn for fifty years. Our guide to comfort fit wedding bands covers how band construction affects fit.

Rings with heat-sensitive stones

Soldering means a torch. Emeralds, opals, pearls, tanzanite and a number of other stones can be damaged — fractured, clouded, or discolored — by that heat, and emeralds in particular are frequently fracture-filled in ways that heat will ruin.

This doesn't make the ring unsizable. It means the stones come out first and go back in after, which is more work and more risk, and it's why an honest jeweler asks what the stones are before quoting anything. Our article on emerald rings and how to care for them goes further into why that stone in particular needs handling.

Shanks that are already worn thin

On a ring worn daily for decades, the bottom of the shank wears down — sometimes to a fraction of its original thickness. Sizing a shank that's already thin puts a solder join into weak metal. The right fix there is usually a new shank, which also solves the fit. If your ring has a visibly flattened or thinning bottom, mention it.

Rings with detailed engraving or hallmarks on the shank

Hand engraving, milgrain, or a date engraved inside the band will be interrupted where metal is added or removed. Interior engraving can often be re-cut afterward — we do fiber laser engraving in house — but antique hand-engraved shanks are a genuine loss, and some pieces are better left as they are and worn on a different finger or a chain.

When sizing isn't possible: the alternatives

"It can't be sized" is rarely the end of the conversation. Depending on the ring, the trade has several other approaches:

• Sizing beads — two small beads of metal added inside the bottom of the shank. They take up a small amount of space and, usefully, stop a ring rotating on a finger where the knuckle is much larger than the base.
• A sizing bar — a hinged or fixed bar inside the shank, for a similar effect with more adjustment.
• A spring insert — a sprung horseshoe inside the ring that lets it pass a large knuckle and then hold snugly. Particularly useful for arthritic knuckles, which is the situation this exists for.
• A new shank — replacing the bottom of the ring entirely. This solves fit, wear and structure at once, and on an heirloom it's frequently the right answer.
• Remaking the ring — for an eternity band or a piece that's beyond economical repair, the stones can be reset into a new ring built to the correct size. If it comes to that, it becomes a custom design conversation, and the original stones carry over.

Which of these is appropriate depends on the ring, and not every ring is a candidate for every option.

Before you assume it's the ring

Fingers change size — genuinely, and more than most people expect. They're larger in heat and smaller in cold, larger at the end of the day than the start, larger after salt and after exercise, and they change with pregnancy, medication and weight over longer periods.

A ring that's snug in July and loose in January is behaving normally. Before having anything altered, check the fit over a couple of weeks, at different times of day, in the cold and in the warm. Size to the comfortable middle, not to the best day. The right fit slides on with mild resistance and needs a small push over the knuckle coming off — if it spins freely or slides off in cold weather, it's too big.

One thing worth acting on quickly: a ring that has become genuinely loose should come off until it's fixed. Lost rings are almost always loose rings.

What happens when you bring it in

We look at the setting, the metal, the stones and the condition of the shank — and then tell you which of the above applies. If it's straightforward, it's routine bench work. If it isn't, you'll get the actual reason rather than a flat no.

Two things worth doing beforehand: know roughly what size you're aiming for, and mention anything you know about the ring's history — particularly if it's inherited, previously sized, or has stones you're unsure about. If it's an engagement ring, it's also a sensible moment to have the prongs checked while it's on the bench; our guide to caring for a ring at home covers what to watch for between visits. And if you're having a ring sized before it's insured or after a stone change, keep the paperwork current — our note on insuring an engagement ring explains why the appraisal matters.

Bring it in and we'll tell you

Most of this is a two-minute answer in person and a frustrating hour online, because it depends entirely on the ring in your hand. Full details of what our bench handles are on our jewelry repair page, or read more about repair and restoration work in Pittsburgh.

Come by 503 Freeport Road, Pittsburgh, PA 15215, or call 412-782-1757 — and if the ring came from a relative, bring anything that came with it. If it turns out the ring can't be saved as it is, the stones almost always can, and we can talk about what it could become instead.
