Who stole my $350k diamond ring?

Paris Hilton 'almost' lost her $350,000 diamond ring during a night out in Poland!

The celebrity DJ went into panic mode when she realized the ring was missing and says she accidentally left the massive diamond-encrusted piece in the vehicle that took her across the tarmac to her private jet.

Hilton explained she was exhausted because she'd performed in Ibiza the night before, then hopped a flight to Poland and worked all day… before heading back to Ibiza.

Lucky for the rich girl, a Polish firefighter found her misplaced jewelry. TMZ says Hilton is extremely grateful to get it back and says she's in the process of getting the firefighter's contact so she can give him a reward and then, send some gifts for his family.
