I was recently proposed to with a beautiful platinum engagement ring, which I love. However, I was given my grandmother's white gold wedding ring when she passed, and I would love to melt and remold it into a wedding band to accompany my engagement ring. My question is this: Will anyone who casually looks at my rings be able to tell a difference between the white gold and the platinum? I don't want the rings to look terrible next to each other, so I'm wondering if this is a good idea or not. Thanks for the advice!
