I have a ring that I made in a size 7.25 for sale; a buyer who is a
size 9 wants it.

The most I have ever stretched a ring is up to 1 full size, with a
roller stretcher. The stone, which is already set, is very unique, so
this would be my preferred option, but I am afraid that stretching it
almost 2 sizes might be too much for the sterling silver.

Does anyone have any advice on stretching?

Am I going to have to pop the stone out and sleeve some more silver
into the band?

thanks,

Either way, rolling or putting in a piece has its drawbacks.
Rolling, which ive done a lots, distorts the band, as well as thinning
it. Risky to true up on your trivet with the stone set .
Putting in a piece into the band is not as good as making a fresh band
for the setting .
Eitherway you would be advised to pop? if its that easy? the stone out
and then do the alterations. Did you leave a hole under the stone to
assist its removal? by some future jeweller?

If it was me, id replace the band and keep the setting.

One trick ive used when putting in a piece into the band is to enclose
the setting in a mass of ball clay nice and soft. weve tons of it here
as our subsoil.( the Romans mined it 2000 yrs ago )
then id put this mass immersed in water with the band sticking out about
3/4in.
Works fine.
