Surveys show when it comes to engagement rings and wedding bands Platinum is her first choice. Because it’s a pure and naturally white metal, unlike white gold that isn’t truly white, platinum will enhance the sparkle and brilliance of a diamond. Platinum won’t fade or tarnish over time. For the guy who’s making the investment in the diamond – platinum will hold that stone more securely, that’s why the world’s most important diamonds are always set into platinum. Look for your wedding bands at the same time as the engagement ring to see how all three rings work together and buy your wedding bands at least six months before the wedding.
