DP has a ring, very special to him. It was his late father's, and when he got married he had it made into a band for his wedding. Since he got divorced he wears it on his right hand. We're planning to marry eventually. I'm not sure whether it would make sense to use it as a wedding ring - we could get another but he's not a jewellery person so wouldn't normally wear two rings, but it would seem odd to reuse it in that way!
