It’s like a table-cut diamond,’ Alexa told More Or Less magazine.The ring’s design reminded her of jewellery worn by figures at the court of Henry VIII, including his famously ill-fated second wife Anne Boleyn.She explained: ‘When I went to the National Portrait Gallery and looked at images of Anne Boleyn and all the other people who perished at the hands of Henry VIII, a lot of them had these rings on.’ Alexa Chung has confirmed her engagement to Sienna Miller’s ex Tom Sturridge as she revealed a bizarre story behind her ‘haunted’ Tudor diamond ring She said the ring’s design reminded her of jewellery worn by figures at the court of Henry VIII, including Anne BoleynBut Alexa’s choice of engagement jewellery prompted an unexpected reaction from a friend while she was preparing for a fashion show in Paris.She recalled that her hairstylist, Alexandri, exclaimed: ‘Oh my god, I think your ring is haunted.’Alexa continued: ‘He took it off my finger and started making wishes around it and blowing on it.
