State Property's 'George' necklace is named after Georgina Kirrin, a character from Enid Blyton's book series The Famous Five - we love that the double-sided design allows you to express your personal style, just as she was known for doing. It's handmade from 18-karat gold and strung with a circular pendant featuring shimmering pavé-set diamonds on one side and glossy onyx on the other.
