Koh-i-Noor
Since arriving in the U.K., it has only ever been worn by female members of the family, starting with Queen Victoria. After Queen Victoria's death, the Koh-i-Noor was set in the crown of Queen Alexandra, the wife of Edward VII. It was used to crown her at their coronation in 1902. The diamond was transferred to Queen Mary's crown in 1911, and finally to the Queen Mother's crown in 1937. When The Queen Mother died in 2002, it was placed on top of her coffin for her state funeral.
