The Princess of Wales could be set to make a dazzling appearance tomorrow.

Princess Catherine is set to enjoy her next tiara moment this week as a state visit gets underway here in the UK. On Tuesday, the state visit from His Majesty Sultan Haitham bin Tarik, Sultan of Oman, will officially begin.
This state visit, to be held at Windsor Castle, will run from Tuesday to Thursday. It will be the first state visit by a Sultan of Oman to the UK since March 1982, when Queen Elizabeth II hosted Sultan Qaboos bin Said.
The state visit this week will come with all the usual pomp and pageantry that state visits here in the UK offer. This will include a formal welcome from King Charles and Queen Camilla on the Royal Dais on Dachetr Road in Windsor.
A carriage procession will then take the royals, including Prince William and Princess Catherine, to Windsor Castle, where they are expected to receive a Royal Salute by a Guard of Honour in the Quadrangle of the Castle. Tatler reports that the royals will listen as the regimental band plays the Omani and British National Anthems, before they inspect the guard and view a military parade.

The royals will then have lunch in the State Dining Room, where other royals are expected to be present, before a special exhibition of Oman-related items in the Green Drawing Room.
On Tuesday night, Princess Catherine’s tiara moment is expected. This is because King Charles and Queen Camilla will host a state banquet for the Sultan of Oman, which various other members of the Royal Family will attend.
The last few state visits have been attended by Princess Catherine and Prince William, who have sparked fan frenzies over the very regal outfits. For Catherine, the state banquet outfit usually includes a stunning royal tiara.
The tiaras worn by the future queen for state banquets before include the Queen Victoria Oriental Circlet tiara and Queen Mary’s Lover’s Knot tiara. The Princess of Wales has also previously worn the Strathmore Rose Tiara and the Lotus Flower Tiara.
Her favourite tiara, which she seems to have worn the most, is the Lover’s Knot tiara. This tiara was originally created for Queen Mary in 1914 by the House of Garrard from pearls and diamonds already owned by her family.

The tiara was a replica of one that Mary’s grandmother, Princess Augusta of Hesse, owned, believed to have been kept in an unknown private collection. After Queen Mary died in 1953, the crown was passed down to her granddaughter, Queen Elizabeth II, according to Town and Country.
The late Queen wore the tiara several times and even allowed Princess Diana to wear it. It is believed Diana loved the tiara, despite how heavy it could be to wear.
While Catherine also loves the tiara, she did not wear it on her wedding day in 2011. Instead, Catherine borrowed the Cartier Halo Tiara to wear on her wedding day.
