The Crown Street store is offering a white gold necklace with a diamond and tanzanite pendant, worth around £700, for the winner and a silver collarette, a Pandora birthstone ring, and a bottle of Champagne for the runners up. More than 2,000 tickets have already been sold with the winners being picked on Magpas Green Day on May 25. Sarah Edwards, manager, said: We just wanted to give something back, and what better way than to a local charity, that you may need some day if you have a car crash. The odds are better than the lottery for some great prizes. INFORMATION: Tickets are £1 each and available at Piggotts Jewellers, 2 Crown Street, St Ives.
