When Kate Middleton was a 25-year-old accessories buyer at London-based fashion chain Jigsaw, she asked jewelry designer Claudia Bradby to create this necklace for Jigsaw's younger customers. "Her vision was quite simple and classic," says Bradby. "She's not a fussy fashionista. She was so straightforward, warm and bright that I remember thinking William was lucky to be going out with her."
