Dazzling in a glittering tiara that once belonged to the Queen Mother, the Duchess of Cornwall looked every inch a Queen-in-waiting at the Commonwealth Heads of Government banquet tonight.
Camilla was lent the exquisite honeycomb-patterned Boucheron tiara by the Queen to mark the historic moment that Prince Charles first hosted the summit in her honour.
Her exquisite turquoise evening gown was by Bruce Oldfield and had a lace and beaded neckline and sleeves.
She was also wearing the Queen's Family Order, her highest personal order of merit, pinned to her shoulder. The order contains an enamelled portrait of the Queen as a young woman surrounded by diamonds and was given to Camilla on her 60th birthday.
Her diamond earring and bracelet were a gift to her by her husband.
Prince Charles was no slouch in the style stakes either.
The prince, who celebrated his 65th birthday yesterday, was dressed in Black Tie with Miniature medals including his Garter Star and Order of Merit neck order.
The royal couple were hosting a banquet for Commonwealth Heads of Government at the Cinnamon Lakeside Hotel in the Sri Lankan capital.
The prince and his wife were welcomed by group of Sri Lankan dancers before attending a pre-dinner reception.
Lining the walk from the Hotel Lobby to the Banqueting Room, which will accommodate the pre-drinks reception and the dinner, were 30 volunteers showcasing Sri Lankan fashion through the ages. The banquet will include two short toasts by Heads of Government, and a return speech by The Prince of Wales.
The menu, which was organised by Buckingham Palace staff, consisted of a Terrine of Grilled Vegetables and a Sauce Vierge to start with followed by a main course of Pan Fried Modha (a local fish) with Nuwara Eliya organic vegetables and a sauce Hollandaise.
For dessert there was a delicious Mango and Chocolate Parfait with a Strawberry Macaroon.
Wines included a patriotic Camel Valley Brut, Seyval Blanc 2010 from Cornwall.
MRS GREVILLE'S JEWELS ... THE STORY BEHIND THE BOUCHERON TIARA
Dame Greville from Boucheron was a well-known society hostess who had a considerable jewellery collection, the crowning glory of which was her tiara.
The honeycomb-patterned jewellery piece was made by Boucheron jewellers for the Hon. Mrs. Greville in 1921 out of stones salvaged from another tiara.
She was a close friend of Queen Mary and, having no heirs of her own, left her considerable jewellery collection to her daughter Queen Elizabeth (the future Queen Mother) when she died in 1942.
It was to became Queen Elizabeth’s signature piece after the King’s death and she wore it consistently throughout her life, well into old age.
Although the tiara was already spectacular when Her Majesty received it in 1942, she improved it in 1953 by having Cartier add height to the top tier in the form of groups of brilliants with one large marquise-cut diamond in the centre.
Since the Queen Mother’s death, the Queen has not worn this tiara (unlike the Queen Mother’s other signature tiara, the Oriental Circlet); instead, the Queen has loaned it to the Duchess of Cornwall.
She has worn it on a number of special occasions including earlier this year when she attended the State Opening of Parliament for the first time alongside her husband.
On the tables were displays of John White orchids and Michael daisies.
The tables were also laid with the 57 Commonwealth silver toasting goblets, part of a matching set provided by each member state of the Family of Nations.
The goblets are engraved with the respective government's national armorial bearings and are used for any occasion where a formal toast is made.
Also on display behind the couple as they greeted their guests was the Commonwealth Mace, a gift from the Roal Anniversary Trust to the Queen on the 40th anniversary of her accession to the throne.
