Simple solitaire bands resize easily, while complex settings with stones around the band do not, so it's important to know this before you buy.
HOW RESIZING WORKS
A jeweller cuts the band and removes or adds metal, though engagement rings complicate this simple concept. Most rings handle one to two sizes, about 2-4mm in circumference, but going beyond this risks structural problems.
Metal matters. Platinum and gold work well, though white gold needs replating afterwards to maintain its colour. Titanium and tungsten carbide cannot be resized at all.
The stone setting determines what's possible. Prong settings resize easily because the work happens away from the stone, while bezel settings need careful handling and tension settings often cannot be resized without compromising security.
WHAT RESIZES EASILY
- Simple solitaires with plain bands, where the stone sits clear of the sizing area
- Classic three-stone rings with side stones sitting away from the sizing area
- Vintage-style rings with top-half decoration that doesn't circle the entire band
- Simple milgrain or basic engraving, though decorative elements may need touch-up work
WHAT CANNOT BE RESIZED
- Eternity bands with stones around the entire band, where the pattern breaks when you add or remove metal
- Channel-set or pavé bands where stones extend partway around
- Intricate vintage designs with detailed filigree or complex metalwork that cannot be reproduced
- Alternative metals like titanium, tungsten, and ceramic
- Tension settings that rely on precise spring tension
THE PROCESS
A good jeweller examines the setting, metal type, and design before committing to the work.
To size down, they cut a section from the band and rejoin the ends. The seam is soldered, filed smooth, and polished so that quality work leaves no trace.
To size up, they insert metal or stretch the existing band. Adding metal works for significant increases while stretching handles minor adjustments.
After sizing, the ring needs finishing work including polishing, possible replating for white gold, and checking stone security.
TIME AND COST
Expect one to two weeks depending on complexity, though simple work moves faster.
Cost varies with complexity and metal type. Simple gold band resizing costs less than complex white gold with replating, while platinum costs more due to its density and working requirements. Complex work involving stone removal or decorative reconstruction can cost considerably more, and sometimes replacement makes more sense.
GET THE SIZE RIGHT FIRST
Accurate initial sizing prevents most problems. Professional sizing accounts for finger fluctuation since fingers are largest in the evening and during warm weather.
Get measured multiple times at different times of day because finger size varies with temperature, time, and activity. Consider your lifestyle since manual work may require a looser fit, and remember that ring width matters because wider bands feel tighter than narrow bands at the same size.
WHEN NOT TO RESIZE
Changes beyond two sizes risk structural integrity and proportions, so consider replacement instead. Some antique or vintage rings have value that outweighs sizing concerns, and multiple resizings weaken rings because each introduces stress points.
Sometimes the cost approaches the ring's value, and replacement may make more financial sense.
WORKING WITH A JEWELLER
Choose one with specific engagement ring experience and get detailed assessments before committing. Honest jewellers explain limitations and risks rather than promise impossible results.
Understand warranty implications since some manufacturers void warranties after third-party modifications, and check insurance requirements because significant modifications may need policy updates.
THE REALITY
Most engagement rings can be resized within limits, though accurate initial sizing beats correction. Simple designs offer flexibility while complex settings face constraints.
Work with experienced professionals who understand ring construction and limitations. Quality work should be invisible while poor work can ruin a ring permanently. Some rings simply cannot be resized safely or cost-effectively, and in those cases, consider ring guards, temporary solutions, or replacement. View our ring size guide.
