"I don't want to ask any questions - I just want to offer a substantial reward to have it back."
Mrs Brown was back in Whanganui during the weekend, and decided to make an appeal for its return.
"Someone could've flogged it off, and someone else legitimately bought it, not knowing it was stolen."
The ring was insured, and she's inquired to have a replica made, but was told it could not be exactly copied.
"And it wouldn't be my mum's ring, anyway."
The ring is an unusual one - white gold and diamonds, with a distinctive leaf pattern on the sides.
