£3m diamonds worn by Rita Ora accidentally left on an easyJet flight

Isn't it annoying when you leave your headphones / jacket / book on a plane? Well, how about £3 million worth of jewellery?

According to AFP, a courier tasked with transporting diamonds for singer Rita Ora to wear at the Cannes Film Festival accidentally left the suitcase packed with gems behind on a flight.

According to The Telegraph the courier in question was on an easyJet flight from to Nice from London Luton airport. The incident, which took place on May 16, saw the courier leave behind perhaps the most expensive suitcase in the world as she disembarked.

She also left behind her coat. Bad day at the office.

Police sources claimed via The Telegraph that the courier quickly realised what she had done and tried to return to the plane. Sadly, it was too late as the plane had already turned around and was heading back to London.

Luckily, easyJet reportedly were able to locate the suitcase and kept it safe until it was delivered to Heathrow airport. Police officers then collected the case of diamonds and it was sent back to Nice.

According to Page Six, a police source joked, “Someone with their head in the clouds nearly lost several million.”

The Telegraph reported that the £3 million treasure trove was loaned to Ora by an unknown London jeweller. While the specific jeweller has yet to be identified, Ora was later seen on May 16 hosting a Magnum VIP party at Cannes where she wore a large Chopard diamond necklace.

The following day, Ora attended the Charles Finch Filmmakers Dinner in Cannes wearing silver earrings, bangles and stacked rings from an unnamed brand.

Ora and singer Liam Payne continued to fuel dating rumours at the dinner, as they were seen laughing and chatting together over the course of the night. Though Ora has since told The Sun that the pair are simply "close friends" and that romance is not her "main priority".
