"Handmade By Me"~ Gold & sterling silver jewellery

There are four usual ways to make a ring bigger

In basic terms below, cheapest (1) first, best (4) last

1 : Ring it stretched using either an expanding tapered shaft, or a roller & re polished

2 : Ring is put on a tapered solid steel stake, and hammered sufficiently to squash the metal which stretches it, then filed to shape & re polished

The above options make the shank ( bottom) of the ring thinner

3 : Cut with a straight cut with a saw blade, and a piece it soldered in, then filed to shape, & re polished

4 : Ring is cut with side cutters, creating a V shape on each end of the shank, this is filed to a neater "V" shape, and a piece of metal slightly bigger & thicker to match is filed with matching inward V shapes (pictures 1 & 2)
This second piece slots neatly into place creating joins of twice the size of a straight cut, and therefore twice as strong.
Once soldered in place the inside is filed to match, Ring can now be place on a tapered stake and the over sized piece hammered down a fraction if required to adjust precisely to required size.,then filed to shape and polished.
Using this technique takes a little longer, and wastes my metal, rather than the original shank thickness.
The result is stronger, the ring is not made any thinner, though with tapered shanks the width may change ever so slightly ( in exactly the same manner as if it had originally been made bigger at production.)
Needless to say, when sizing products I mainly use option 4
Apologies for the poor artwork, I am mightier with the blowtorch & files than I am with a pencil or camera.
Main picture is with piece soldered in and slightly hammered but before filing to shape
Last picture ring has been filed to shape, ready to be polished
