For the full year, Blue Nile reported net sales of $400.0 million, compared to $348.0 million for the full year of 2011, an increase of 14.9%.

"The fourth quarter caps off a great year of growth at Blue Nile, building upon our sequential growth while posting greater profitability versus the prior year. Investments we made in 2012 paid off with the highest annual levels of revenue growth and customer acquisition in five years, exceptional strength in engagement sales in the U.S., and a return to strong growth internationally. While we fell short of our expected sales of non-engagement jewelry during the holiday season, in part due to a weaker environment for consumer discretionary spending, we gained valuable insight that will guide the evolution of our product mix. We believe that our strategy to accelerate this part of our business is on track," said Harvey Kanter, President and Chief Executive Officer.
