Ring Resizing: What It Costs and What Is Possible

Most rings can be resized, but not all, and the method used affects both the cost and the finished appearance.

Sizing down

To make a ring smaller, the jeweller cuts a section from the bottom of the shank, rejoins the ends and solders the seam, then cleans and polishes it. Done well, the join is invisible. Sizing down by one or two sizes is routine work.

Sizing up

To make a ring larger there are two approaches. The jeweller can stretch the band on a mandrel, which works for up to about half a size on a plain band and slightly thins the metal. Beyond that, the shank is cut and a matching piece of metal is soldered in. Adding more than two sizes usually means the whole shank is replaced.

What cannot be resized

• Full eternity rings, where stones run the entire circumference.
• Tension settings, which rely on precise spring pressure in the metal.
• Rings with intricate patterning, engraving or milgrain running all the way round.
• Tungsten carbide, ceramic and most titanium rings, which cannot be soldered.
• Some rings with delicate inlays or wood, which will not survive the heat.

For these designs the only options are a replacement in the correct size or, for tungsten and ceramic, exchange schemes that some manufacturers offer.

Typical cost and time

A plain gold or silver band is the cheapest job. Adding metal, working in platinum, or removing and resetting stones adds to both the price and the turnaround. Most high-street jewellers quote three to ten working days; complex work with stone resetting takes longer. Prices vary widely by country and metal, so get a written quote before agreeing.

Protecting stones

Heat is the enemy. Emeralds, opals, pearls and many treated stones can crack or discolour when soldered near. A competent jeweller will remove vulnerable stones before working and reset them afterwards, which is why quotes for stone-set rings are higher. Always ask specifically how the stones will be handled.

How many times can a ring be resized

Two or three times over a lifetime is generally safe. Each resize removes or adds metal and repeats the heating cycle, and eventually the shank thins. If a ring has already been resized twice, a new shank is often the better investment.

Before you book

Confirm the target size in millimetres rather than a national code, so there is no ambiguity between the sizes used in different countries. Ask whether hallmarking needs to be reapplied, whether the original finish will be matched, and whether the work is insured while it is out of your hands.
