Tiffany Most Exposed to Luxury Slowdown

With Europeans and Asians buying fewer $65,000 diamond necklaces and $10,000 amethyst earrings, Tiffany & Co. may be in for a less-than-glittering 2012, as no U.S. luxury merchant is more exposed internationally. The world's second largest jeweler generates almost half its sales outside of the Americas, up from 38 percent in 2006, according to data compiled by Bloomberg.
