Kate Moss was so smitten with a bracelet she spotted at a recent London wedding that she bought it — straight off fellow guest Ann Dexter-Jones‘ arm. “She was so crazy to wear it,” Dexter-Jones recalled to us, that Moss’ pal, billionaire retailer Sir Philip Green, “insisted Kate have it immediately and bought it for her right off my wrist.” Not that Dexter-Jones minded: she designed the black onyx, black diamond, solid gold and silver bauble, as part of her new jewelry line. “And [Moss] gave me her Chanel bracelet as a gift, so that my wrist wasn’t bare,” Dexter-Jones said. Her line debuts this weekend at The Webster during Art Basel.
