Jewelry is such a personal thing, and maybe no piece more so than a ring. Wedding bands are worn for years and years—decades and decades, if we're lucky—and have been the most popular men's rings since, well, forever. Traditional men's wedding rings are simple bands of yellow or white gold (or a combination of the two) and sometimes have diamonds in them. More modern versions may be made from metals like platinum or titanium or feature inlaid designs or semiprecious stones. Depending on your personal preference, any of these styles could be worn as men's engagement rings or promise rings as well.
