And the winner of the night’s best bow tie goes to… Uggie! The adorable star of The Artist stole the spotlight during the movie’s Best Picture win at the 2012 Academy Awards with his custom 18-karat gold and silk bow tie by Chopard. The pup-size accessory featured an engraving of his name and will be auctioned off to benefit The Amanda Foundation, a non-profit organization for rescue dogs and cats. “I was completely charmed by Uggie’s role in The Artist,” said Caroline Scheufele, artistic director of Chopard. “Knowing that Uggie is a rescue dog, it inspired me to create a unique piece to benefit an important cause.” Too cute!

Mad Men star Christina Hendricks sparkled in 193 carats worth of Chopard diamonds on her earrings and two bracelets, which added a touch of shine to her red one-shoulder gown by Romona Keveza look. But after she walked the carpet and entered the auditorium, Hendricks noticed that one of her bracelets fell off and went missing, Page Six reports. Thankfully, only briefly! The 124-carat diamond bracelet (bottom bracelet shown inset), estimated at $850,000, was found by an event worker and is now safely back in the hands of Chopard.
