\r\n \r\nThe UK Jeweller of the Year finalist had designed and made the ring for the charity, which gives children with life-threatening illnesses the chance to achieve one of their dreams.\r\n \r\nThe auction took place at the Valentine 'Make-A-Wish' Ball at the Dorchester Hotel in London on 11 February. Bobby based the diamond ring on a design taken from his new Star Cross'd Lovers collection \u2013 the silver and black enamel Star Cross'd Wishes ring, which is now on sale with 50 per cent of the profits also going to the Foundation.\r\n \r\n"It's a fantastic charity," said Bobby. "It does incredible work, granting magical wishes to children and young people in the UK diagnosed with life-threatening conditions. I am honoured that Make-A-Wish UK invited me to design these special pieces."\r\n \r\nGuests that also attended the event were Make-A-Wish UK CEO Neil Jones (pictured with Bobby) and Harry Potter actors James and Oliver Phelps.
