The Queen Consort wore a diamond thistle brooch gifted to her by the late Queen in a poignant tribute to Elizabeth II.

Camilla choose the heirloom – a nod to the Scottish national flower – for her mourning outfit as she attend the service of thanksgiving at St Giles’ Cathedral in Edinburgh on Monday.

The Queen gave the glittering piece, which depicts two thistles, to her daughter-in-law.

It is believed to have belonged to the Queen Mother, and has been worn by Camilla on a number of occasions, particularly for visits to Scotland.
