Sophie Countess of Wessex is a senior figure among the royal family. She is wed to the Earl of Wessex, and lives in Windsor with him and her two children.
Kate Middleton caused a stir when she wore a mystery set of jewellery to a diplomatic reception at Buckingham Palace in mid-December.
The huge sparkling diamond pieces were soon revealed to be from the Diamond Chandelier Drop Demi-Parure.
The Diamond Chandelier Drop Demi-Parure is thought to be a gift from a Middle Eastern ruler, and it was worn by the Queen when King Fahd of Saudi Arabia visited the UK.
However, Kate is not the first royal to have been loaned these stunning jewels from Her Majesty.
Sophie wore the earrings and the necklace from the set to welcome Donald Trump to the UK in June at the state dinner in Buckingham Palace.
Sophie Countess of Wessex was given a tiara by the Queen for her wedding day.
It is believed the design was commissioned specially for her by the Queen.
The unique diamond design consisted of three peaks and was made from jewels from the royal collection.
Eddie LeVian, CEO of jewellery Le Vian, told Express.co.uk: “If you look closely, the tiara is composed of four anthemion elements – these are sections composed of twisting diamond floral motifs, set on a gold frame.”
