A grieving grandmother is searching for the one item that made her feel close to her late granddaughter.

Deborah Key's granddaughter died four years ago. Since then, the Cleveland woman has kept the child's cremated remains in a necklace. But that necklace was lost during a recent shopping trip.

Now, Key is hoping that the power of social media will help return what was lost.    

"I have carried her next to my heart for the four years she's been gone, so it feels kind of naked not having her there," she said.

It's been almost a week since Key has been without her most prized possession: a necklace, holding ashes of her granddaughter, Alice, who was delivered stillborn at 28 weeks.

Key has worn the necklace every day, until it somehow fell off while shopping with her son and grandson in Cleveland last week.

"We've pretty much been everywhere," she said. "I've talked to managers in stores. But so far, we've not had any leads."

Key has retraced her steps since Nov. 5, the day the necklace went missing.

She made stops at The Dollar Tree and A Cloudy Forecast (on Treasury Drive), both Cleveland Goodwill stores (Paul Huff Parkway and Keith Street) and the United Grocery Outlet.

Key hopes an employee or shopper might spot the necklace and realize that it's more than just a piece of jewelry.

"They might not realize exactly what it is. It's a different-looking necklace, and you can see the vial with her cremains in it," Key explained. "I'm hoping that by getting it out there, if they find it, they'll understand what it is and the importance of it."

Key's "Missing Necklace" post has been shared over 1,000 times on Facebook, from folks in Cleveland and across the country.

Se hopes the power of social media reunites her with her granddaughter's memory.

"I would love to have it back, most definitely," she said. "It just, I don't know. You feel incomplete with her gone."

If you happen to find the necklace, Key is offering a $100 reward.
