The mystery is partially solved…
Convinced that my finger couldn’t possibly have shrunk in the past two weeks, I ventured in to the city to visit the jewellers and ask them why my wedding ring is falling off. The ring was checked against the order form, tick, no problem. The finger was re-measured, uh-oh… It seems that somehow my finger was measured as a “P” but this was then transcribed somewhere as an “R” — two sizes larger. Not surprisingly, a ring two sizes too big will fall off when I shake my hand! Much apologies all around, me for not checking when we picked it up, them for causing the problem. A resized or remade ring will be available in about ten days.
