THINK PINK DIAMONDS

Some people dream of owning a Lear jet but for me it would be a huge blossom-pink diamond. These beautiful accidents of nature can be found in shades from raspberry to delicate sea-shell. So rare are large pink diamonds that only a few have ever been documented and their history reads like a who's who of intrepid explorers and royalty. During the Golden Jubilee look out for a glimpse of the world's most perfect pink diamond, owned by The Queen, set in the centre of a flower spray brooch, This pure 23.60 carat gem, mined in Tanzania, was presented as a gift to Princess Elizabeth in 1947 before her wedding by royalist mine owner Dr John T. Williamson. Ever since, the stone has been called the Williamson Pink and was set by Cartier into an impressive jonquil–shaped flower with curved petals, leaves and a stem in diamonds: a dazzling white cluster surrounding a flawless pink bloom.
