The main stone is a 5.56ct cushion-cut Mozambican ruby, set with 2 heart-shaped diamonds and set with round brilliant-cut diamonds. An intense passion for diamonds has been the driving force in Laurence Graff’s life since he first sat, over 60 years ago, at a jeweller’s bench in Hatton Garden, London’s jewellery quarter. His story of metamorphosis is very similar to that of a diamond – transformed from raw, rough carbon into a precious, ravishingly refined gem. ‘I have always been fascinated by diamonds,’ he says; ‘I remember looking at them, studying them closely to understand their purity, and the way they had been cut. It was an inherent feeling that has turned in to a lifelong passion.’
