Some useful hints and tips when stretching/ reducing…

One must appreciate there is a number of sizes a ring can be stretched. Some particulars to remember is the type of metal, gold, silver, platinum etc ( the softer the metal the more it can be stretched as it is less rigid, metals like platinum are far harder to stretch than say 22ct gold), also the method the ring has been constructed. A plain cast wedding band has no solder join therefore a 22ct ring can be stretched up to 1 to 8 sizes.

Having a solder join on a ring creates a weak point so therefore when over stretching is preformed it will come apart from the join (the weakest point).

At times, depending on the your experience and the type of ring, you may have to add metal to enlarge the ring size. Therefore a stretching tool may not be appropriate (we have a large selection of tools and equipment catering for this process see below).

To spot a solder join, heat the ring to near a cherry red colour then place in water you will notice a colour change line (this is where it has been soldered). Heating a ring up does soften it & so helps the ring stretch process to be perform easier.
With gem set rings there is more risk of either damaging the stones or the setting while heating or stretching. To protect gem stones while heating it is a good to cover the stones with cool heat to protect them (see link below).

The upright ring stretcher is suited to plain bands, any attempted to stretch gem set rings runs the risk of them falling out, also on the reducer plate gemstones can get damaged.
The most suited tool for stretching gem set rings is the (roller type) gemstone ring stretcher (see below for models and info).

Remember any type of stretching done using these tools may leave some after marks so finishing is required (see links below).

Ring Adjusting - Economy Ring Stretching Tool

Tapping insert with a hammer expands the mandrel and allows enlargement to 6 sizes.

This is an incomparable and economical way to stretch rings with minimal expense. The ring stretcher comes in three parts, tapered mandrel, stepped opening collet and wooden base.

How to use:
  • Place the ring to be stretched on the stepped opening collet
  • Push the tapered mandrel into the collet and place on the wooden ring stand
  • Now tap with a hammer (code: H19525) the taper will start opening the collet thus stretching the ring
  • A good way of controlling the stretch with more accuracy is use a G- clamp (code: C33518)
  • Instead of tapping with a hammer, the G clamp on each turn will accurately stretch the ring
  • For sizes M to Z + 6

Ring Adjusting - Gem Ring Stretching Tool, Indian Made

Gem ring stretcher ideal for a jewellery retail shop.

The idea of this tool is that it will compress the metal of your ring shank for gemstone rings thus expanding the size of the ring.

How to use…

1. The base has to firstly be secured to your work surface by screwing it down with long screws or nuts and bolts on to a work surface (not supplied).
2. The unit has a selection of half round and “V” shaped dies.
3. Depending on the shape, size and thickness of the shank you want to stretch. Choose a die that fits in with little movement against the rig shank.
4. To fit this die into the unit, pull out the holding pin on the top of the stretcher. You will find the die and gear nearest to the open/closing handle can be removed.
5. Place your selected die on top of the gear and fit back into the stretcher locking it with the holding pin.
6. Place the ring between the two rollers and turn handle clockwise. The rollers will start meeting both sides of the ring. Once both rollers are touching the ring shank securely hold handle and move left to right 45 °.
7. Perform in smooth actions about 3 to 4 times.
8. Take the ring off and measure size, if still too small repeat the process with another dies that fits.
9. The more you turn handle to close die and tighten on the ring and swing left to right determines how much the ring shank is being compressed. (hence ring size increasing).

  • 15 dies in a plastic storage box
  • Steel construction
  • Sizes stretching capacity H to Z + 6
  • Overall size 95mm x 195mm x 90mm
  • Weight 1400 grams

How to use reducer plate…

The reducer plate is a very handy feature incorporated with this stretcher. The use of the press with plate compress a ring shank to a smaller size. Notice on the reducer plate there is a selection of tapered machine holes to suit different ring shank sizes.

To reduce your wedding band place your ring on the tapered hole so it sits in with it half in and out.
Move the reducer plate so it meets the top of the planishing drop die (the circular plate that moves down towards the reduction plate when handle is pulled down). Pull handle down so it pushes the ring into the taper. This is slightly compressing the shank thus making it smaller. Repeat this process moving the ring round to keep the sizing even and regular in space.

Please note: Additional finishing will be required. It is not advisable to reduce patterned wedding bands as they can be easily marked. (see code for ring stretcher reducer for pattern wedding rings seizer tool from Bergeon Switzerland)
