You don't want it. He can't have it back," That's the motto of exboyfriendjewelry.com, a Web site where women can sell the jewelry left behind by the jerks who dumped them—or whom they kicked to the curb. Even better, almost, they can tell the world their terrible stories. "I found out he's been leading a double life and cheating on me the whole time (one of them was even my friend ... well, ex-friend)," writes someone calling herself "loveisblind" on the site. She's selling her 19k white gold, Canadian-diamond engagement ring for $3,500, noting: "C'est la vie."

Megahn Perry, 31, of Sherman Oaks, Calif., and her stepmother, Marie Perry, 44, of Encino, launched the project last February when Megahn, after her own divorce, could not decide what to do with her vintage wedding ring. Within two months their site had 2.5 million hits and 5,000 registered users. Sellers can donate their proceeds to a breast cancer charity if they wish. The Perrys, who don't charge for postings, make money selling advertising. And while they love their site, there are limits. That fabulous silver bracelet Megahn received from a new boyfriend last March? "I'll never sell it," she says. For now.
