“Were these just any rings I could accept this, but one of them was gift from my Mum,” the 27-year-old wrote. “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 then wrote that if anyone has any information to email: findthering@outlook.com. The actress also included a picture of the rings including a close-up of her mother’s ring.

Watson said her mother’s ring helped inspire jewelry she wore in the Disney live-action film "Beauty and the Beast," according to Buzzfeed.

“The costume designer saw that I had one which my mom had given me, and she was like, ‘Can I design one for Belle?’ because Belle’s mother dies when she’s really young,” Watson told the outlet.

“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.”
