Never wanted one for myself even though as a jeweler I think the art of it is just spectacular. I've done the artwork for several for my brother but just never seen or thought of anything I wanted with me forever.
My wife has a peace lilies, birth/death date, and Lily in script (our stillborn daughter's name) on the inside of her left wrist as a remembrance piece. She wants a couple others in remembrance of other people who have passed recently but she hasn't narrowed down exactly what she wants yet.
