A sombre Princess Kate was a vision of ethereal grace as she sported a black wool Catherine Walker & Co coat dress with silk piping and a traditional mourning veil crafted from black netting for the occasion. Holding her composure, the mother-of-three looked effortlessly elegant in the all-black ensemble, adhering to royal mourning protocol. Prince William looked equally smart in military attire.

Princess Kate's large brooch is composed of three leaves, each of which are outlined in yellow gold. A sizeable mabe pearl is positioned at the centre of each leaf, which are finished with a scattering of small diamonds.
The brooch was a sweet nod to her husband Prince William's late grandmother. The rarely-seen accessory was previously worn by the Queen during her er visit to South Korea in 1999.

In 2017, Princess Kate donned the eye-catching brooch during a visit to Belgium for the 100th anniversary of Passchendaele, and it has remained in her jewellery box ever since.
The choice of brooch worn by the princess is symbolic, too. Oak has often been an important symbol linked to Royalty, signifying longevity, strength, power, loyalty, and stability; all qualities the Queen was well known for.
Gemologist Alexandra Michell from Prestige Pawnbrokers of Channel 4's Posh Pawn told HELLO! the brooch is worth an estimated £65,000.

Though the style rule is only set in place during the period of mourning, it is up to the bereaved how long they decide to continue wearing black – a tradition thought to have been started by Queen Victoria.
After her husband Prince Albert died, the former monarch only wore black for the remaining 40 years of her life.
