One woman is having a very merry Christmas, indeed, all thanks to the honesty and determination of a complete stranger.

“When I saw it, I said, ‘God, this is really a pretty      .Somebody's going to heartbroken,” said Shirley Grandey , 62, who was a volunteer for keeping the environment clean.

When Grandey was        a large pile of pine needles and dirt at the end of her hard work day, she never       to come across someone's diamond ring lying alone among a pile of         .

Knowing the ring probably had special         , Grandey held onto the jewelry and made it her 16 to find the owner.

“I said, 'Oh God ,I have to find the        , "'recalled Grandey before making the decision to contact the TV station, to help         the word. "It was definitely a          ring.  It was intertwined（缠绕）and had their         on it．”

Her efforts        ．

“The brother of the girl saw it on          and told her," said Grandey, who couldn't have been happier to return the          ring to its original owner, Julie Sanalitro.

“I was screaming and running around the house,” Sanalitro told the news station. "We always come to        our tree from there to celebrate Christmas Day," she said.

When Sanalitro called to         the ring, she explained it was a gift from her boyfriend, who had only given it to her two months ago when they            reunited.

She was not only able to          answer all of Grandey's questions about the ring,         she was the original owner, but Grandey added, “I knew it was hers the moment she was walking up.”

“We just hugged each other and she had a few tears," the         volunteer explained.

All that Crandey asks from this         is simply for people to “pay it forward.”  She said. “ I would want someone to give it back to me if I lost my ring, so just try to pay it forward.”
