I suppose that there is no one answer to this. When my wife passed away at home the police removed her rings before taking her away. I sort of understand why, but I have a feeling that they should stay with her at her resting place. We wore matching wedding rings for the past 24 years and the engagement ring was heart shaped to represent my love for her.
I have trawled the internet for help on what is appropriate but many comments on other sites have sounded heartless along the lines that this would be a stupid waste.
I know this is a very personal question, but I really would appreciate comments on what some of you have done.
