The Queen welcomes the public to Buckingham Palace on Saturday for the annual opening of the state rooms.

This year, to celebrate her Diamond Jubilee, a special exhibition includes an unprecedented display of the Queen's personal jewels - those inherited by Her Majesty or acquired during her reign.

Jenny Hill took a look at some of the highlights with curator Caroline de Guitaut.
