Tiffany Launches Legal Tiff With Costco

One of the world's leading luxury brands has filed a suit against one of the world's largest discount retailers over allegedly false claims on engagement rings. Tiffany & Co. is suing Costco Wholesale Corp. to find out how many of the supposedly counterfeit rings the big-box retailer sold, the source of the rings and, of course, for monetary damages. This suit could have the same result of a similar 2004 charge that Tiffany leveled against eBay. In that case the court said it was Tiffany's responsibility to figure out the source of the counterfeit jewelry, not eBay's.
