Something to bear in mind when you're deciding how much to spend on an engagement ring: Etiquette and tradition notwithstanding, courts usually say that the ring should go back to the buyer in the event that the wedding gets called off. Not that some people are deterred from clinging on to a valuable bauble, though, like Sharon Bush (left), W's former sister-in-law, who famously refused to return the 11-carat, $243,040 canary diamond ring that the late investor Gerald Tsai proposed to her with, even after he filed suit to get it back.
