“As of now they are missing,” the actress writes. “Were these just any rings I could accept this, but one of them was a gift from my Mum.”
She continues, “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 pleaded with readers to return the rings if they were found, writing, “I cannot express how much it would mean if they came back to me – no questions asked. If you have seen them or have any information please email: findthering@outlook.com.”
The actress’ mom, Jacqueline Luesby, is a lawyer in the U.K.
The Harry Potter star told Buzzfeed in March while promoting her latest film that her mother’s ring served as inspiration for Belle’s own jewelry, specifically, a ring that “would sit on her little finger.”
“The costume designer saw that I had one which my mom had given to me, and she was like, ‘Can I design one for Belle?’ because Belle’s mother dies when she’s really young.”
She added, “Anyway, I was really proud of the ring and thought it was so beautiful that I asked if I could keep one and they said I could.”
