Crafted out of stones from unused items such as swords, the necklace is made up of 25 cushion cut brilliant diamonds and an impressive central drop jewel - the 22.48 carat Lahore diamond. The necklace was commissioned by Queen Victoria, and made by Garrard in 1858, and it has been worn at every coronation since. The Queen has also worn it to formal events and for her for her Diamond Jubilee portrait.
