My boyfriend and I are planning to get engaged this year. We have beautiful Tacori rings picked out already. Now, we're unsure if we should get our rings in platinum or white gold. We want our rings to stay shiny and beautiful. I've heard that white gold can turn yellow after a short time. I'm also concerned about the diamonds in my engagement ring and wedding band falling out. We can splurge on the platinum but only if it's really worth it. Please help! What are the real pros and cons?
