A jeweler can enlarge or reduce a ring by one or two sizes without it showing. The method depends on the metal, the design and the stones.

![Steps of the technique: Measure, Cut the band, Add or remove, Solder, Round, Polish](https://www.711grados.com/media/diagrams/ajuste-talla-steps.en.svg "Summary of the steps")

## Enlarging

The band is cut, opened with a stretcher or a piece of metal is added, soldered, rounded on the mandrel and polished.

## Reducing

A segment of the band is cut, closed and soldered, and rounded and polished.

## What cannot be resized

Tungsten or ceramic bands and certain designs (stones all around the band, tension settings) do not allow resizing, or only very limited.

## Alternatives

Sizing beads or bars inside the band, as a temporary fix.

## Step by step

1. **Measure.** On the ring mandrel.
2. **Cut the band.** At the bottom.
3. **Add or remove.** A piece of metal.
4. **Solder.** With the right solder.
5. **Round.** On the mandrel.
6. **Polish.** And check.
