Memento Mori Stories

I have a turquoise ring I got, somehow, from my father’s mother. I truly don’t remember how I came to have it – what the exact circumstances were - but I have had it for over 40 years, and have worn it consistently at some points, and not at all at others. I have wondered for some time how this particular grandmother came to have this ring. Did she buy it? Was it given to her? Why a Southwestern style ring for someone from Northern New York? It seems strange to me that I never asked her these questions, or if I did ask her, why I don’t remember the answers.
