I have just done it, received funds through paypal, but not posted it yet
My grandmother (paternal) wasn't very nice. She was very narcissistic and emotionally abusive to my dad. He was very screwed up for a long time over his childhood. She was vile to my mum (and all the spouses of her children) until my very patient, loving mother refused to have anything to do with her.
After she died they found she had labelled a few of her bits of jewellery, including a ring with my mum's name. It's a small gold ring with an opal. Not worth much (I did some research, in the condition it was in, between £100-200) and too small to wear. Mum gave it to me a few years ago.
I have a ring from my GM, which i wear every day. I also have my aunt's ring which is from that side of the family, which is quite valuable, beautiful and meaningful because I loved my aunt.
I'm broke. So I sold this ring and got £120 for it. How morally objectionable is that? I didn''t tell my parents. I doubt dad ever had a clue I had this ring, and mum won't care.
