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.”
