THE nation has entered a period of mourning following the sad announcement that Her Majesty the Queen passed away at the age of 96 yesterday afternoon.
The Royal Family will likely be seen wearing black during this time out of respect for the monarch - and we have seen Kate Middleton and Camilla wearing white pearls for a very important reason.
And Kate - wearing her £425 18ct gold baroque pearl earring - was seen for the first time since Her Majesty's passing, as she picked up her kids, George, Charlotte and Louis, from school.
White pearls are the jewellery that is officially worn during the mourning period by the family.
They are often referred to as “mourning jewellery”, and this dates back to Queen Victoria’s reign.
For the ceremony, Kate wore an iconic Japanese Pearl Choker necklace, paired with Bahrain Diamond and Pearl Drop earrings from the Queen’s collection.
Meanwhile, the Queen paid tribute to her husband wearing a three-strand pearl necklace and matching earrings.
Her Majesty also opted to wear pearls to the funerals of Princess Diana, Princess Margaret and King George VI.
Leslie Field, the author of The Queen's Jewels, told : "Pearls are traditional for Queens going back one thousand years- there has never been a Queen who didn’t wear pearls.
“They were rare, beautiful and lustrous and the more you wear them, the more lustrous they become.”
As well as wearing pearls, we could also see royal women choosing other jewellery pieces that pay tribute to the Queen, such as ones from her collection.
