Former Hollywood star Winona Ryder is at the center of a new controversy after reportedly losing $125,000 worth of borrowed Bulgari diamonds loaned to her for an awards ceremony appearance in Spain. The actress had been given a diamond-encrusted bracelet and ring to wear to a Marie Claire magazine party in Madrid earlier this week. She reported the items missing after allegedly handing them in to her hotel's front desk in an envelope to be kept in the venue's safe. But according to the French magazine Voici, the hotel bosses have not yet been able to locate surveillance footage to prove Ryder's claims, and Bulgari executives have now asked police to investigate the jewelry disappearance. A spokesperson for the aging star, who was arrested in 2001 for failing to pay for goods taken from Beverly Hills California store Saks Fifth Avenue, has yet to respond to requests for comment. Bulgari representatives have refused to address the reports or confirm the disappearance of the jewels.
