New York | LVMH Moët Hennessy Louis Vuitton is already one of the world's biggest luxury goods empires. Now it is interested in adding yet another high-end name to its coterie of brands: Tiffany, the famous seller of engagement rings and other jewelry.

LVMH approached Tiffany & Co. in recent weeks with an all-cash bid of about $US120 a share, according to two people with knowledge of the matter. That values Tiffany, which has its headquarters in a famous Fifth Avenue building in Midtown Manhattan, at about $US14.4 billion ($21 billion).
