On 19 March 1986, Prince Andrew (fourth in line to the throne at the time) and Sarah Ferguson announced their engagement. Prince Andrew had known Ferguson since childhood, and they had met occasionally at polo matches, and became re-acquainted with each other at Royal Ascot in 1985. Also prior to their engagement, Ferguson had accompanied Diana, Princess of Wales, during her official tour of Andrew's ship HMS "Brazen". Prince Andrew designed the engagement ring himself. It consisted of ten diamonds surrounding a Burmese ruby. He chose the Burmese ruby to complement Sarah's red hair. With her fun spirit and friendly approach she was initially considered to be a good addition to the royal family.
