The year 1992 was a bad one for the royal family. In addition to the three royal marriage breakdowns, a fire wreaks havoc in Windsor Castle causing major structural damage. The queen would later describe this year as "annus horribilis."
Criticism of the monarchy peaked in 1997 following the death of Princess Diana in Paris. The royal family was accused of being remote and out of touch with the grief-stricken public. However, after several days of silence, the queen returned to London, speaking to mourners and admitted there were lessons to be learnt from Diana's life.
Since the death of Diana, the queen's popularity has enjoyed a revival as she continues to preside over what appears to be a softer, more accessible modern royal family. Here, she attends her grandson Prince Harry's graduation from the Royal Military Academy at Sandhurst, southern England in 2006.
The Imperial State Crown is worn by the monarch at the end of the coronation ceremony, and at formal occasions including the annual opening of Parliament. The current version was made in 1937, and is set with some of the most famous stones in the collection, including the Cullinane II, or Second Star of Africa diamond, and the Black Prince's Ruby. The pearls suspended from its arches are said to have been Queen Elizabeth I's earrings.
Queen Alexandra's Crown was designed with eight arches, a style typical of her native Denmark. It was originally set with the Koh-i-Nur diamond, which is now in the Queen Mother's Crown -- today it is set with paste stones.
The Sovereign's Sceptre with Dove dates back to 1661; the bird symbolizes the Holy Spirit.
The annointing of the new monarch, using holy oil, is one of the first parts of the Coronation ceremony. The Coronation Spoon is the oldest of the Crown Jewels -- it survived the Civil War, and dates back to the 12th century.
The Crown Jewels collection also contains items created for banquets. This enormous gold salt cellar, in the shape of a castle, was presented to King Charles II after the Civil War by the citizens of Exeter.
British monarchs are symbolically "married" to the country during their coronation. This coronation ring was made for Queen Victoria, as the traditional one was too large. However, this version was too small, and became stuck on her finger.
This tiny crown -- which stands less than 10cm tall -- was made for Queen Victoria after the death of her husband, Prince Albert, in 1861; it was designed to be worn over her widow's veil.
