Royal diamonds to be displayed for queen's jubilee The Girls of Great Britain tiara, worn by Queen Elizabeth II at a state banquet on Nov. 22, 2011, will be on display this summer as part of a exhibit highlighting her diamond jewelry. (CBS) A dazzling display of royal diamonds is going on display at Buckingham Palace this summer, in honor of Queen Elizabeth's Diamond Jubilee, which marks her 60th year on the throne. "Diamonds: A Jubilee Celebration," will explore "the ways in which diamonds have been used and worn by British monarchs over two centuries," the palace said in a statement, and will feature an "unprecedented" display of the queen's personal jewels - those inherited by the monarch or acquired during her reign.

The necklace is made of 25 cushion-shaped brilliant-cut diamonds with a 22.48-carat drop pendant at its center. The 1,187-diamond miniature crown worn by Queen Victoria - the only other British monarch to celebrate a Diamond Jubilee - for her official Diamond Jubilee portrait in 1897 will be on display, along with the South Africa necklace, given to the current monarch on her 21st birthday in 1947. Also among the items set to be displayed is the Girls of Great Britain tiara, given to the queen as a wedding present by her grandmother, Queen Mary, who herself received it as a wedding gift in 1893. BBC News reports that the piece is known as "granny's tiara" and is among the queen's favorites - she wears it often, most recently at a state banquet in November. The exhibit will begin in August and is currently scheduled to run through September, with additional dates to be added. Adult tickets will cost 18 pounds (about $28). Other events taking place this year for the queen's Diamond Jubilee include a flotilla on London's River Thames, a concert at Buckingham Palace and members of the royal family making trips around the U.K. and to countries around the world.
