Emma Watson asks people on Facebook to help her find her missing ring

Emma Watson is pleading for your help.

The Harry Potter star lost three silver rings while visiting a spa at London's Mandarin Oriental Hotel in Hyde Park.

On a Facebook post detailing the incident and appealing to her millions of fans, Watson said she accidentally left the rings in a safe inside the locker after receiving treatment, and security checked the safe the morning after but there was nothing in it.

The 27-year-old explained she's desperate to find one ring in particular because her mother gave it to her.

As of now they are missing. Were these just any rings I could accept this, but one of the them was a gift from my Mum. She bought it the day after I was born and wore it for 18 years, never taking it off, and then gave it to me for my 18th birthday. I wear this ring everyday, it is my most meaningful and special possession.

Watson said there would be "no questions asked" if someone handed the rings back to her.

She even set up an email account: "If you have seen them or have any information please email: [email protected]."

A spokesperson for the Mandarin Oriental Hyde Park said: “The matter is in the hands of the relevant authorities and we are doing all we can to support them with their enquiries.”
