We already have my wedding band because my e-ring and band are a set that have been in my FI's family for generations. Obviously, we didn't choose the metal that my rings are set in, but I absolutely love them. My question is, my band is set in platinum, but we can't afford a platinum band for my FI. I suggested we use white gold, but he says he prefers yellow gold. Is this a big deal? I always though wedding bands were supposed to somewhat match to show that the two of you go together. Thoughts?
