It is totally personal preference. DH has a cool titanium ring, with black, gold and silver. I love his ring, but I have a diamond band. If it is important to you, you could probably get the same style ring, just yellow and white gold. You may even want a unique stye, no one would realize they are two different colors. This way, you have the same ring, but with your own preferences. You could also get inexpensive matching bands to wear during special occasions.
