I feel no attachment to mine. At all. I just want them gone.
My set of rings no longer has the center stone, but I can't get rid of mine to save my life. One guy at a gold shop said I'd do better selling it online but that's a wasteland. Said the best he could do was $150. For rings that I bought myself.
I'm taking him up on it so I can build bookshelves.
I'm glad you got healing out of it. You might as well get something.
