Queen Elizabeth inherited most of the tiaras she own and she left them alone. (Unlike her grandmother Queen Mary, who loves to redesign her gems regularly) The queen commissioned the tiara in 1973 from Garrard using gems which she already had in hand. The gems were 96 rubies from the people of Burma which she received as the wedding present and the diamonds from the Nizam of Hyderabad tiara which was also the wedding present. The rubies were a symbiolic gift. Rubies are believed to protect the owner from illness and evil and from 96 diseases that affect humans according to Burmese beliefs. The queen wears the tiara often since its commission.
