A charm bracelet sits on display in the window of a Pandora A/S jewelry store in Copenhagen, Denmark, on Thursday, Sept. 12, 2013. The Danish jeweler, which has gone from stock market darling to disaster to darling again since its 2010 initial public offering, is taking a page from fast-fashion retailers like Zara, which introduces designs as often as twice a week.
