Nothing says diamonds quite like the gridiron. Three jewelry-makers spent $42 million on spots during November and December NFL games last year, targeting the men who plan to propose and the women who watch football -- the NFL fanbase is 45% female, according to NFL Network Director of Sales Brad Van Nostrand. Wedding planning was down this year -- the unlucky '13 was partially to blame, according to TheKnot.com -- so an uptick in weddings and jewelry-ad spending is expected heading into 2014.
