Unwanted bequest, what do you think

Would you rather her have taken it out of obligation and then it end up in a dump, handed over to a stranger, dumped in a charity shop?

It meant something to you and your mum but other wise it's just an item.

One of my mums sayings is ‘Pearls bring tears’. An old wives tale I expect. So she says that pearls should never be given as a present. Maybe your aunt feels this way?

I agree with Allsorts, please don't be offended. A touching gift, but perhaps she thought the pearls should stay within your family.

Clearly your aunt either doesn't understand the sentiment behind your mother's gift or doesn't have the same sense of sentimentality as you. I think it's a bit odd to turn down something in these circumstances, but you've dutifully offered her the pearl choker, so you can't do any more. I'd see if anyone else in the family would like it.

Your aunt could have put it better but maybe was thinking that someone that would really appreciate it should have the pearl choker.

Better her telling you than selling it or giving it away.

Please don’t be hurt, your aunt was being insensitive but probably doesn’t realise it. Not enough to cause problems, you are grieving for your mom and she doesn’t know what’s happened.
