The Duchess of Edinburgh looked wonderful on Tuesday night when she made an appearance at a Buckingham Palace state banquet honouring the Emir of Qatar Sheikh Tamim bin Hamad Al Thani and his wife Sheikha Jawaher bint Hamad bin Suhaim Al Thani during their state visit to the UK.
Duchess Sophie, 59, was seen wearing the Wessex Aquamarine Necklace Tiara as she arrived at the palace for an evening hosted by King Charles. The shimmering diadem features an aquamarine diamond and is one of royal's most featured tiaras.
It's believed that Prince Edward's wife helped with the design of the tiara and she has previously been seen wearing the stunning jewel at King Charles' first State Banquet as monarch.

Also in attendance were the Prince of Wales, the Princess Royal and the Duke and Duchess of Gloucester.

Sophie wore a bottle green couture gown from Suzannah London elevated by the Lotus Flower Tiara on loan from her sister-in-law Queen Camilla, as well as the incredible Diamond Chandelier Drop Earrings and Necklace.

The floor-length gown was accessorised by the Aquamarine tiara. Expert jeweller at F. Hinds, Jeremy Hinds recently told HELLO!: "As one of the Dutchess' go-to tiaras, it is reported that the piece was designed bespoke for Sophie, by jewellers Collins and Sons. As this is part of a personal collection and not from the royal vault, you won't see this piece on any other royal."
