The Real Reasons Why Queen Elizabeth's Diamonds Are So Precious

The iconic headpiece was made in 1937 for the coronation of George VI, and reduced in height for that of his daughter the Queen. It contains 2,868 diamonds, 17 sapphires, 11 emeralds and 269 pearls, but the most impressive feature is the 317.4 carat Cullinan II diamond - the second largest cut from the original stone - which sits in the crown's band.

Set with emeralds, sapphires, rubies, pearls, 365 rose cut diamonds and a whopping amethyst, the cross-embellished orb (seen in the Queen's left hand) was created to represent Christ's authority over the world, and has been used for every coronation since 1661.

A symbol of the monarch's role as head of state, the scepter was created in 1661, and it contains the largest cut diamond in the world. The 3,106 carat Cullinan diamond was discovered in 1905, and the fist-sized stone was the biggest ever found. After it was gifted to King Edward VI it was broken down into several pieces. The largest - the 530.2 carat Cullinan I, also known as The Star of Africa - was set at the top of the scepter, while the other Cullinan were used mostly in brooches.

It may not be the biggest, oldest or most expensive in the Queen's collection, but her engagement ring is sure to be the piece of jewelry closest to her heart. It is made up of a 3 carat brilliant cut diamond with smaller stones either side, and all were taken from a tiara that had once belonged to Prince Philip's mother.

For the earrings, the 12 and 7 carat main stones were in 1830 taken from an Indian armlet made from twisted silks, and commissioned by Queen Victoria to be worn alongside the Coronation Necklace. The Queen usually wears the earrings with the matching necklace as a set for formal occasions.

As seen on stamps, coins and bank notes, this crown was made in 1820 and was worn by George IV on the way to his coronation. The diamond-encrusted roses, thistles and shamrocks represent England, Scotland and Northern Ireland, and there are a total of 1,333 diamonds incorporated in the piece, along with pearls and a pale yellow diamond at the centre of the front cross. The Queen first wore it for the State Opening of Parliament in the year she acceded to the throne, and then to her coronation, as well as many times since.

The tiara is set with with brilliant and rose cut diamonds and was made by royal jewelers Garrard. The style is Russian and was very popular with the royal family in the first half of the 20th century. The Queen borrowed it from her mother for her wedding day.

The Delhi Durbar was a commemoration in India to mark the accession of King George V, and called for a little something special for his Queen Consort Mary. The necklace is set with eight cabochon emeralds - three cushion shaped, four oval and one lozenge shaped - and six large brilliant cut diamonds with a double platinum chain set with 94 brilliant cut diamonds, and more on the chains which suspend the whopping emerald pendant, and the marquise cut Cullinan VII diamond.

For day-to-day life the Queen favors three strands of pearls, but for special occasions such as a State Opening of Parliament, or official visits, she favors the three strands of diamonds her father gave her in 1950, when she was a 24 year old princess. The 105 brilliant cut diamonds were used from a collection of loose stones that had previously been used to lengthen existing necklaces in the royal collection.
