Ring from broken marriage

Desiree

My mother in law gave me her second wedding ring from her marriage to my husbands dad. They aren't married anymore. It is a very pretty ring But gold isn't my thing at it is a size 5. I wear a size 9 and don't think they can go up to that size. Do u think if they can't go up to a size 9 i should keep the ring like it is or possibly ask his mom if i could take the diamonds out and put them in a new setting? Please help
