More than 10,000 diamonds owned by six monarchs over three centuries have gone on display at Buckingham Palace to mark the Queen's Diamond Jubilee.
The exhibition includes a number of the Queen's personal jewels and works from the royal collection chosen for their artistic significance and their historic importance.
Several pieces of jewellery, such as the Delhi Durbar Tiara, Queen Victoria's fringe brooch and the Kokoshnik Tiara, are on display for the first time.
The exhibition includes jewellery made from the world's largest diamond, the Cullinan diamond, which weighed 3,106 carats as an uncut stone.
The exhibition also features several pieces commissioned by Queen Victoria, the only other monarch to celebrate a Diamond Jubilee.
One of the highlights is the miniature crown she wore for her official Diamond Jubilee portrait in 1897, which contains 1,187 diamonds.
Exhibition curator Caroline de Guitaut described the exhibition as "an opportunity for people to see some of the most remarkable diamonds in royal possession".
There is a mixture of the Queen's jewels that she wears on a regular basis and also diamond covered works of art.
In both instances, these show us how monarchs have deployed diamonds to give an aura of magnificence and an aura of sovereignty and show the wealth and power of our nation.
This year we are celebrating Her Majesty's Diamond Jubilee and therefore this is a perfect opportunity to give visitors to Buckingham Palace a wonderful opportunity to see so many treasures.
The Diamonds: A Jubilee Celebration exhibition is part of the summer opening of Buckingham Palace and will run from June 30 to July 8 and July 31 to October 7.
