Her Royal Highness Sheikha Mozah Bint Nasser Al Missned, Queen of Qatar was one of the many royal guests to attend a lunch hosted by the Queen for monarchs from 26 countries at Windsor Palace to commemorate her Diamond Jubilee.

She looked sensational wearing a dress designed by London-based couture house, Ralph & Russo.

The custom-made full-length teal silk gown with tulle overlay and three-quarter-length sleeves was accented with a dazzling beaded waistband.

Other coordinating pieces included a turban, peep-toes and earrings.
