The mother took to Facebook to ask everyone to keep a look out for the necklace which fell off her neck while she was out for lunch on Valentine’s Day in New York. Hundreds of people including Davina McCall have shared the post in a bid to return the precious piece of jewellery to Vicky.
In her Facebook post, the mum said: "We were seated upstairs in Applebee's Restaurant for lunch (think it's 6th / 7th Ave) and it was definitely ON when I arrived there as I adjusted it in bathroom and touched fingers with Alice - something I frequently do. That was around 1.30pm, Valentine's Day."
Alice died in 2013 from a blood cancer aged 17 and the necklace contained her fingerprints . Before her death, the youngster published a ‘bucket list’ of things she wanted to do before she died including whale watching in Canada and meeting Take That.
The inspirational youngster also founded her own charity Alice’s Escapes which provides holidays for seriously ill children, raised £100,000 for charity and met David Cameron who was on board with her request to encourage everyone to sign up as a bone marrow donor.
