There are a couple of key things your groom should know:
1) If he's right-handed, he'll never get an accurate wedding band fit on that hand because the left-hand ring size is usually a half or even a full size smaller.
2) His band does not have to match yours.
3) A plain gold band is the logical choice, but there are lots of great choices that can still be "conservative" or "traditional" without being boring. It's a look we kept in mind when selecting the styles we show here, but of course we also made room for some wilder options that incorporate rogue materials like ebony, green diamonds, and metals like titanium, tungsten, and cobalt.
