After the tears and days of listening to “All by Myself” on repeat, breakups often boil down to one thing: who keeps what. That was the catalyst behind Ex-Boyfriend Jewelry (exboyfriendjewelry.com), a site that helps you get rid of baubles and mementos that, like their giver, you never want to see again.

“You sentimentalize these items,” says Megahn Perry, who started the site in February with her stepmother after being disappointed by the offers from pawn and consignment shops for an engagement set she, um, no longer needed. She decided to sell it online and include the reason she was giving it up—turning her sob story into a selling point. The lure of cold, hard cash has generated posts ranging from a $500 diamond ring from a couple who “married too young and decided we wanted different things” to a garnet sparkler given by a “guy [who] is a lying, cheating, egomaniac ass.”

The site offers a place where people can pillage others’ disastrous relationships for rings, necklaces and “Gifts That Should Have Been Jewelry” (“He sucked and so does the Roomba!”—sold for $150). In addition to hawking old gifts and generally getting over their exes, buyers can contribute to the Good Karma Fund, which benefits the Susan G. Komen Foundation.

Perry insists that selling used jewelry is not taboo. In fact, she says that numerous men have bought rings from the site to propose with. It can even be a cathartic experience.“It’s a great place for people to vent,” she says. “We’re trying to create a fun, tongue-in-cheek way of moving on.”
