No giggling at the back!
Recently married, my lovely wife took my wedding ring to the high street jewellers where it was bought today - I wanted it reduced, if possible, by half a ring-size.
We were expecting the shop to have to send it away to a workshop to have a little slice of metal removed, the ring then welded back together, and rebuffed to perfection.
Instead, a man at the counter immediately disappeared to a backroom for about ten minutes, and returned with the ring, claiming to have shrunken it by the desired amount.
It looks/feels identical to me, the Mrs didn’t ask what technique the man had used - and it wasn’t a scam as such, as there was no charge, and an offer to adjust the ring further if need be. Is there some easy non-metallurgical backroom resizing process this bloke could (claim to) have used?
