The Halo Scroll tiara was created by Cartier in 1936. Prince Albert, The Duke of York, purchased it for his wife Elizabeth. Later, she passed it to their daughter Princess (later Queen) Elizabeth as an 18th-birthday present. The Queen's sister, Princess Margaret, also wore this tiara frequently for royal events.

In the portrait above, the Queen's daughter Princess Anne wears the tiara for a formal sitting. It was lent to Kate Middleton, the new Duchess of Cambridge, upon her April 29th wedding to Prince William.

Queen Mary's "Girls of Great Britain & Ireland" tiara

This tiara was given to Princess May of Teck as a wedding gift. Lady Eve Greville's committee raised the money from "the girls of Great Britain and Ireland" for the tiara, which garnered more than £5000.

May, a German princess, was engaged to Prince George, son of King Edward VII. She would be known later in life as the formidable Queen Mary, Queen Elizabeth II's mentor in all things royal.

Queen Mary instructed Garrard's to create this tiara in 1914, copying the design of a tiara worn by her grandmother, Princess Augusta of Hesse-Cassel.

Princess Augusta married her second cousin, Prince Adolphus, the Duke of Cambridge. He was one of the many sons of King George III.

Augusta's tiara was set on a base of pearls to match the hanging drop pearls that were suspended from diamond lover's knots. Queen Mary's redesign did not have a base of pearls, but diamonds instead.

This tiara was frequently worn by Diana, Princess of Wales during her marriage to Prince Charles. It was a gift to her from Queen Elizabeth II, and it became one of Diana's most famous accoutrements. After Diana's passing, the tiara reverted to the possession of the Queen, who may pass the tiara to the new Duchess of Cambridge.

This tiara was said to be made for King George III for his wife, Queen Charlotte. However, the "Russian Fringe" tiara, made by E. Wolff & Co. for Garrards, was actually created in 1919 for the future Queen Mary.

Created by the famed jewelers Garrards in 1870 for Lady Poltimore, this grand tiara was famous mostly for its more recent owner - HRH Princess Margaret. The children of the late Princess, Viscount Linley and Lady Sarah Chatto, sold this and other items at an auction at Christie's in 2006.

The Princess, who died in February of 2002, wore it for her wedding to Anthony Armstrong-Jones, Lord Snowdon. Like many of the tiaras in the Royal Family, the Poltimore tiara was seen in several alternative forms such as a diamond fringe necklace and as brooches.

Queen Alexandra, the wife of King Edward VII, commissioned Garrard's to create this tiara in the style of a Russian peasant girl's headdress. Her sister Princess Dagmar, who had become Empress Marie of Russia, had a similar tiara which was the inspiration for the Kokoshnik. It is composed of sixty-one platinum bars and filled with 488 diamonds. It is often worn by HM The Queen today.

This tiara is a genuine Russian article, made by a Russian jeweler for the Grand Duchess Vladimir. During the Russian Revolution, the Duchess moved with her family to safety while her jewels were hidden in a vault in the Vladimir Palace. The looters never found the treasure, and a member of Britain's Secret Intelligence Service friendly with the Duchess' family managed to rescue the jewels and send them back to her.

The Duchess commissioned the tiara to have Oriental pearl drops, as seen in the first image. This is the original design. When Queen Mary bought the tiara from Princess Nicolas of Greece, Duchess Vladimir's daughter, she had the last of her Cambridge emeralds made into drops and set in the tiara (above). These emeralds are interchangeable with the pearls, and both styles are worn by Queen Elizabeth II.

The diadem is worn by Her Majesty on state occasions such as the Opening of Parliament. The Queen is seen wearing the diadem on certain coins. It was originally made for HM King George IV in 1820, and has undergone many extensive repairs throughout its lifetime. Garrard's carried out a complete refurbishment in the early 1990s, restoring it to full glory.
