Fourth crowned portrait of HM Queen Elizabeth II facing right, wearing the Girls of Great Britain and Ireland tiara.

The Girls of Great Britain and Ireland tiara was a wedding present in 1947 from her grandmother, Queen Mary, who received it as a gift from the Girls of Great Britain and Ireland in 1893 on the occasion of her marriage to the Duke of York, later George V. Made by E. Wolfe & Co., it was purchased from Garrard & Co. by a committee organised by Lady Eve Greville. In 1914, Mary adapted the tiara to take 13 diamonds in place of the large oriental pearls surmounting the tiara. At first, Elizabeth wore the tiara without its base and pearls but the base was reattached in 1969. The Girls of Great Britain and Ireland Tiara is one of Elizabeth's most recognisable pieces of jewellery due to its widespread use on British banknotes and coinage.

ELIZABETH II DEI GRATIA REGINA FIDEI DEFENSATRIX means Elizabeth II, by the grace of God, Queen and Defender of the Faith.

Saint George (between 275–281 AD to 23 April 303), according to legend, was a Roman soldier of Greek origin and officer in the Guard of Roman emperor Diocletian, who was sentenced to death for failing to recant his Christian faith.

According to the legend, the narrative episode of Saint George and the Dragon took place somewhere he called "Silene", in Libya. The town had a small lake with a plague-bearing dragon living in it and poisoning the countryside. To appease the dragon, the people of Silene fed it two sheep every day. When they ran out of sheep they started feeding it their children, chosen by lottery. One time the lot fell on the king's daughter. The king, in his grief, told the people they could have all his gold and silver and half of his kingdom if his daughter were spared; the people refused. The daughter was sent out to the lake, dressed as a bride, to be fed to the dragon.

Saint George by chance rode past the lake. The princess tried to send him away, but he vowed to remain. The dragon emerged from the lake while they were conversing. Saint George made the Sign of the Cross and charged it on horseback, seriously wounding it with his lance. He then called to the princess to throw him her girdle, and he put it around the dragon's neck. When she did so, the dragon followed the girl like a meek beast on a leash.

The princess and Saint George led the dragon back to the city of Silene, where it terrified the populace. Saint George offered to kill the dragon if they consented to become Christians and be baptised. Fifteen thousand men including the king of Silene converted to Christianity. George then killed the dragon, and the body was carted out of the city on four ox-carts. The king built a church to the Blessed Virgin Mary and Saint George on the site where the dragon died and a spring flowed from its altar with water that cured all disease.
