There are priceless gifts and then there are priceless gifts. A team of firefighters and civil servants gifted Ozzy Osbourne with a cross constructed of rubble culled from the World Trade Center in the immediate weeks after the 9/11 attacks.

The Prince of Darkness was actually holed up in a New York City hotel when the Twin Towers were attacked by terrorists 10 years ago, but his actions after the events caused him to earn a token of appreciation from rescue workers.

With 10th anniversary commemorations of 9/11 upon us, Ozzy's wife Sharon spoke about her memories of the attacks on her show 'The Talk' on Thursday, revealing how Ozzy received such a special memento.

"That morning we went downstairs for breakfast," Sharon recalled. "The kids and I. And we’re in the dining room and there was Mayor Bloomberg. And then all of these men came and whispered in his ear and he went off. We [went] upstairs and we’re watching the news and then we see what the whole world saw."

Mrs. O got more specific, saying, "I can remember the day that it happened: we went up to the roof of the hotel and we were looking down Fifth Avenue. There was nothing. There was nobody. There were no birds. There was nothing. It was silent. And that silence is terrifying." The family quickly fled the Big Apple and drove cross-country to Los Angeles.

Despite fleeing to the West Coast, Ozzy was haunted by the devastation he had witnessed back East, so he returned to play a concert for the firefighters and first responders who risked their lives to save others.

The civil servants were so touched by Ozzy's actions that they gave him the very special present. Sharon revealed, "They made him this cross, which is made of one of the girdles from the South Tower."

Sharon revealed that the precious cross was constructed of material that was still hot to the touch. "When they gave it to him, it was two weeks later, literally, this isn’t an exaggeration, it was still warm (from the burning)," she said.
