If you're Ellen Barkin, you just place a call to Christie's and the jewelry your ex-husband gave you nets $20 million and some nice vengeful publicity. But for lesser mortals, several websites dedicated to re-selling engagement rings and jewelry from defunct relationships have sprung up, reports Bloomberg News: IdonowIdont.com, for example, secured one (obviously not very) lovelorn mortgage broker two thirds of what he paid for the diamond ring he snatched back from his ex-fiancée. Even better, IdonowIdont eases the process with videos of break-up songs and bitter stories from readers: "It is good for the seller to move on," says the site's CEO, "and there are people who want something vintage and used." It's basically a public service! Albeit one that stomps all over romance and is probably making Miss Manners consider retirement.
