Is it proper for me to wear my mothers wedding rings? My mother just passed this week and my father gave me my moms rings. Is it proper to
Wear her wedding rings on my right hand?

This is only my opinion, but yes. I wear my grand mother’s wedding bands on my right hand, in a way I will always have her with me, just by simply looking down at my hand. I can look and them and get a clam piece of mind when things are going terribly wrong.

First who really cares what anyone else thinks. If you want to do it, it is no one else's business.

Next sorry but there are no "rules" to what is right or wrong with many things. A lot of things are culturial according to your nation of origin.

So if you want to go for it.

For our family we made them into memory wall box that hung in the husbands home until his death. They helped him though a lot of long days. But he wanted you to have them, not to sit in a box I am sure.

Sounds cool to me. I don't see anything wrong with it as long as that's what you want. ;)
