Kate Middleton Wears Queen Elizabeth's Brooch to London Service Honoring Late Monarch

Kate Middleton is carrying the memory of Queen Elizabeth close to her heart.

The new Princess of Wales, 40, was photographed wearing a brooch owned by the late monarch on Wednesday as she made her way from Buckingham Palace to Westminster Hall, where a service was held in honor of Queen Elizabeth, reported Lauren Kiehna, writer & editor of The Court Jeweller.

As shown in a photo shared by The Court Jeweller, the Queen wore the diamond and pearl leaf brooch in Seoul on April 21, 1999, affixed to a yellow ensemble with a white print. She accessorized her royal glamour further with three pearl necklaces.

Along with the special brooch, Kate was pictured Wednesday wearing her late mother-in-law Princess Diana's Collingwood pearl drop earrings, Kiehna reported.
