AND THE BAND PLAYS ON

A diamond isn’t always forever. But what do you do with your bling after you break up? Wedding ring resale Web site IDoNowIDont.com has the answer: Heal that broken heart with some cold hard cash.

The site, founded by New York siblings Josh and Mara Opperman, provides a place where wedding bands can be bought and sold.

The Oppermans started the site last year after Josh’s fiancée left him – leaving behind the ring he used to propose. Frustrated with his options for reselling the rock, Josh and his sister decided there had to be a better way.

“When I went to sell back the ring, I was only offered 35 percent of what it cost,” says Josh. “I didn’t want to take such a huge loss.”

So Josh hit the Web with IDoNowIDont.com. He shared his story and soon started reselling rings from hundreds of people who were in the same predicament.

The site works a lot like eBay. Sellers post their rings with descriptions, photos and starting-bid prices. When a ring is sold, it is shipped to the company’s offices where a gemologist examines the color, clarity and carat weight of the diamond. Only then is the diamond sent to the buyer for its second shot at love.

This step is what, according to Josh, separates I DoNowIDont from other resale sites. “There is absolutely no way someone can get scammed,” he says.

But besides security, the site offers something else you won’t get with just any wedding ring – a story. Sellers have the option of including the history of their ring in the description. Why? “Honestly, it helps to sell the ring faster,” says Mara. “People relate to stories and want to help the person.”

There are tales of 10-year-long relationships, amiable divorces, financial struggles and, of course, infidelity: “My girlfriend’s ex-husband was a doctor. She supported him through medical school, then found out he cheated with many, many nurses. She hates nurses now.”

The stories give buyers an idea of where the ring has come from, but they might do something for the people selling the jewels, as well. “I thought a story would give the ring a better chance of selling,” says Kelly, a 26-year-old from Ohio who sold his ring on the site last month. “But I guess it also helped me to let go somehow.”
