Peoples Jewellers made another bid for Zales.

Peoples said that it and a new partner had offered $50 a share in cash, or about $544 million, to acquire Zale Corp., a Dallas-based jewelry retailer that had rejected three earlier offers that Peoples had made on its own. Peoples, a Toronto-based retail jeweler which holds a 14.4% stake in Zale, said it was joined in its latest bid with Swarovski International Holding AG, a diversified industrial holding company based in Zurich, Switzerland.
