Can a ring be made bigger or smaller? What a jeweller does (and doesn't)

An inherited ring that won't pass the knuckle, a wedding band that's grown tight over the years, a gift in the wrong size. The question is always the same: can it be fixed? Usually yes — but the solution depends a lot on the ring.

Resizing techniques

Stretching or compressing

For small differences, the ring goes onto a mandrel (a steel cone) and the band is stretched with a hammer or a dedicated machine. To go down slightly, it can be compressed. It's quick and leaves no join, but it has limits: stretching thins the band. On a thin ring, stretching too far weakens it.

Cutting and adding metal

To go up further, the band is cut at the bottom and a piece of metal of the same type and thickness is added. It's soldered on both sides, filed and polished until the join disappears. Done well, it doesn't show.

Cutting and removing metal

To go down, a small segment of band is removed, the ends joined and soldered. Generally simpler than sizing up.

Rebuilding the shank

When the band is very worn or the change is large, it may be worth replacing the lower part with a new one. This also fixes rings whose band has thinned after decades of wear.

Rings that need special care

Rings set with stones all around (half or full eternity): there's no free area to cut without disturbing the setting. Often they can't be resized, or need part of the ring remade.
Rings with heat-sensitive stones: some stones and pearls can't take soldering heat and must be removed first.
Rings with continuous designs: engraving, texture or filigree all round. Possible, but the pattern must be recreated at the join.
Gold- or rhodium-plated rings: heat and polishing affect the plating, which may need redoing.
Steel, titanium, tungsten or ceramic rings: generally can't be resized by a jeweller.
Hollow or very thin rings: dent and break easily; reinforcing the band may be the answer.

How much can it change?

There's no single answer: it depends on width, thickness and design. Stretching only suits small differences. With cutting and adding metal the margin is much wider, but a big change can alter the ring's proportions — a ring designed for a slender finger can look small on a large one.

Alternatives

Wear it on another finger. Sometimes the simplest fix.
Sizing beads or bar for slightly loose rings: small bumps inside the band that hold it better without changing size.
Remodel it. A ring that doesn't fit can live on as a pendant. Read how to remodel heirloom jewellery.

Before you ask for a resize

Measure the size you need carefully — see our guide on how to find your ring size. Resizing twice is always worse than once.

At the atelier we assess every ring before touching it and explain the best option. Send us a photo through our ring resizing service and we'll reply with a quote.
