As the name implies, a ring stretcher is a jewellery tool specifically used to enlarge the circumference of a plain ring band, simply by stretching it. They come in many different forms and prices vary enormously; however for the purposes of this article, we are focusing specifically on the Rathburn ring stretcher, which is ideal for both beginner jewellery makers and expert jewellers to increase the size of a ring.
Wondering how to resize a ring at home? Find out how to use a ring stretcher below to make sure you get the right fit.
How does the Rathburn ring stretcher work?
The Rathburn ring stretcher comes in two parts, an outer section which consists of a series of flexible segments and an inner shaft which fits down the centre. As the inner shaft is pushed down with the help of a hammer, it forces the outer segments to splay out which is what stretches the ring.
It is a simple but effective action, which is easily completed in just a few seconds. However, it is worth noting that, as this is a small and portable jewellery tool, it will need to be secured in a vice before any hammering is attempted.
How to use a Ring Stretcher?
Before learning how to use the Rathburn ring stretcher, you will need to check the size of the ring in question – the Rathburn ring stretcher is only suitable for use with ring sizes P, R, U, W, Z, Z+3 and Z+5.
Once the ring size is confirmed, follow our simple steps on how to use a ring stretcher:
- Place the ring onto the ring resizer, making sure it sits flat on the tool.
- Hit the central shaft of the ring stretcher with a hammer, using only a single blow in the initial instance. The outer sides of the tool will expand out, and stretch out the ring to a larger size.
- Take the ring off the tool, re-check the size and then repeat the process if necessary to ensure you reach the right fit.
More ring resizing tips
Now you know how to use a ring stretcher, it’s important you bear these key points in mind when using a ring resizer:
- Measure the ring carefully before attempting to stretch it, and be very clear about the size you want to achieve before you get started.
- The Rathburn ring stretcher tool, and many similar versions, are not suitable for rings with stones. You risk serious damage to both the stone and the ring if you ignore this warning, so make sure you use ring stretchers with plain ring bands only!
- Always anneal a ring before trying to stretch it, to make it more pliable and less liable to snap.
How many times can a ring be resized?
Don’t try to stretch the ring too far. This is not an exact science, but the general rule of thumb is no more than two sizes, and only if the ring is thick enough to withstand such a stretch. For example, if you have a very thin gauge of metal on the ring you want to stretch, it will only move a small amount before it snaps – so exercise caution at all times, and work gradually and steadily.
