Should I swap something for it?

My mum wants to give me my grandma’s wedding ring as my wedding ring. It’s old, beautiful, traditional and my fiancé’ and I have no money for such things. I bought my wedding dress and shoes secondhand. My dress cost $400, my shoes cost $25. The ring is perfect and I’d love it. I was just wondering if I should swap something, like give her the sapphire and diamond ring from my grandma, or the musical jewellery box. Nana loved mum like she was her daughter, so she’d approve of my giving something to replace it and my mum might like it.
