Resizing and Repairing Rings: What Is Possible

Rings are worn closely and for a long time, so they need attention now and then. Fingers change, bands thin and prongs wear. Many problems can be fixed, though some designs limit what can be done.

Resizing

How it works

To make a ring larger, a jeweller cuts the band, adds a piece of metal and joins it. To make it smaller, they cut out a section and rejoin the band. Then the ring is polished.

Which rings can be resized

• Plain bands and solitaires: usually by a size or two, and often more.
• Bands with a decorative section: it depends on how much plain metal is available.

Which rings are hard or impossible to resize

• Full eternity rings, with stones all the way round, because cutting the band would damage the stones. See anniversary bands and eternity rings: a guide.
• Rings with stones set low in the shank.
• Tension settings, where the stone is held by the band's pressure.
• Rings with engraving or patterns that run all the way round.
• Some platinum or very hard metals, which are harder to work.

Half and three-quarter eternity rings can often be resized a little.

Limits

Resizing by more than a couple of sizes can distort a design, especially when it has a pattern. Large changes may need a new shank. Ask about the limits before you buy a ring that you may need to adjust.

Common repairs

• Retipping prongs: adding metal to worn prongs. See how often to check your jewellery prongs and clasps.
• Tightening a stone: adjusting prongs so a loose stone holds.
• Replacing a missing stone: matching the size and colour.
• Fixing a thin or cracked band: adding metal or replacing a section (a new shank).
• Re-polishing: removing scratches and restoring shine.
• Re-plating: renewing the bright finish on white gold.

Questions to ask first

1. What can be done, and what are the risks?
2. How long will it take?
3. What will it cost?
4. Will the ring need to be rehallmarked?
5. Will my stones be removed, and how are they protected?
6. Is the work covered by a service policy or a warranty?

Hallmarking after repairs

When a jeweller adds metal, the piece may need to be rehallmarked, depending on the work. Ask how it is handled. See BIS hallmark marks explained.

Gold, platinum and size

Gold is easier to resize. Platinum can be resized, but it is harder to work and may need a specialist. See platinum 950 jewellery.

Before you hand it over

• Photograph the piece.
• Get a receipt that records weight, stones and condition.
• Agree the work and the price in writing.

Common questions

How long does resizing take? Simple jobs may take a few days. Complex ones take longer.

Will resizing weaken the ring? A well-done join is strong, but repeated resizing can thin a band.

Can I resize a wedding band? Usually, as long as it is not a full eternity band.

Plan ahead

If you are choosing a ring that you may need to resize, ask in advance. See how to measure your ring size at home. Book an appointment for a check, or browse our diamond rings.
