The Queen wore a brooch from the collection of her late mother: the Centenary Rose Brooch.

The brooch, which is made of hand-painted rock crystal and set with 100 diamonds, was the Queen's gift to mark her mother's hundredth birthday in 2000. She inherited the brooch not quite two years later when the Queen Mother died.

Princesses Beatrice and Eugenie made their customary Ladies' Day appearance, but neither wore any significant jewelry. How would you accessorize these outfits?
