New owners of half-carat diamond may not know what's in their g

MURFREESBORO, Tenn. -- Someone found a diamond in the rough at a car dealership and doesn't know it.

Alexander Chevrolet in Murfreesboro conducted a "Digging for Diamonds" sales promotion earlier this month. People who test drove a car had the chance to hunt through sand for one of 100 shiny stones.

Ninety-nine of the stones were $15 cubic zirconia. The other was a $1,200 half-carat diamond.

Alexander general manager Kevin Pratt said all the stones have been found, but the new owner of the diamond is probably unaware of it. Those who found stones were instructed to take them to a local jewelry store for appraisal.

"If someone drew the diamond, they didn't come to Bell Jewelers and have it tested," Pratt said. "So someone is walking around with a half-carat diamond and doesn't even know it."

Greg Tidwell, a co-owner of Bell Jewelers, said he was surprised that only 10 or 12 people have been to the store for appraisals.

"It would be a shame to have such a beautiful diamond not being worn," Tidwell said. "It needs to be on a finger or a necklace or something."
