Emma Watson asks fans to help find missing rings

Emma Watson has issued a desperate plea to fans to help find her missing rings.

The Harry Potter star placed her beloved jewellery in a safe during a recent visit to a plush London spa, but forgot to retrieve them after her treatments.

After realising she had left them behind once arriving home, she phoned security at the Mandarin Oriental Hotel Spa, who revealed they were no longer there.

The actress has posted photos of the rings on her Facebook page, offering a reward for anyone with information leading to their safe return.

She wrote on Facebook: "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."
