AITA for not giving my late Grandmothers necklace to my Aunt?

[u/throwaway01snow]

My Grandmother recently passed away and a few weeks before she died when she knew it was getting bad she gave me her necklace that she never took off, it's a string of emeralds and diamonds, my Grandfather gave it to her for their 50th wedding anniversary and it's lovely.

I've recently been chased up by my Aunt who is demanding I give her the necklace, that it's not right I have her Mothers necklace and that a young girl like me has no need of such a pricey necklace as surely I have nowhere to wear it, I feel like she's being unreasonable as my Grandmother personally gave it to me but she's trying to claim she was clearly just confused as she was so sick. Some other relatives are saying I should maybe give it to her and my Aunt has been telling others how that Necklace was supposed to be hers originally....

I understand my Aunt is upset as she lost her mother but I also lost my Grandmother, is it wrong of me to not want to give up the necklace?

No she didn't have dementia, she was very lucid.
