Garrard Jewellers

Garrard is the official jewellers to British royalty and claims to be the world's oldest jewellers. Some of their famous pieces include crowns for Queen Victoria and Queen Elizabeth II, engagement rings for Princess Diana and Sarah Ferguson, and the Premier League trophy. They have a beautiful web site.
