As part of an aggressive move to become a national advertiser, diamond brand Hearts on Fire, which markets what it calls "the World's Most Perfectly Cut Diamond," has purchased $2 million of national TV advertising on NBC during the Olympics and on USA Network. The 30-second commercials, "Hero" and "Cake Topper" will air a total of 23 times from Feb. 11-13 and reach 30 million people.

"Hearts on Fire is moving toward becoming a significant national advertiser, and this marks a start to that," said David Knies, vp-marketing. "We are running our luxury creative in big-event settings like the Olympics that will reach millions."
