The brooch, which Camilla wore to a Service of Thanksgiving for the Queen, originally belonged to the Queen Mother. The dazzling diamond piece depicts a thistle, Scotland's national flower, and proved the Queen's affinity for the country where she spent her final days.
Queen Elizabeth inherited the accessory in 2002 after her mother's passing. Camilla was first seen wearing it in public in 2015, and it is unknown when the Queen gifted it to her daughter-in-law.
