Today, a dazzling tiara worn by two British monarchs and King Farouk's Star of Egypt diamond are among the historic jewellery exhibits that will be auctioned by Christie's.
The sale will also feature the largest private collection of JAR jewellery ever to come to auction.
The Bessborough Diamond Tiara, which was worn at the coronations of King George VI in 1937 and Queen Elizabeth II in 1953 is the exhibited tiara in tonight's auction.
It was made by Parisian jeweller Chaumet who received orders from Vere Ponsonby, the ninth earl of Bessborough, to design a tiara for his wife on the occasion of his appointment as Canada's governor-general in 1931.
It was made with platinum and weighed 136.5 grams.
Christi's Head of the Jewellery department Max Fawcett told AFP: "This is as iconic as it gets in terms of the style. The workmanship is unbelievable."
He added: "This is quite crown-like, which is fitting for this year as it has been through two coronations."
"It's a piece of art and a piece of history."
It is expected to fetch between 800,000 and 1.5 million Swiss francs.
While the Star of Egypt is a rare and huge 105.52-carat diamond. It appeared for the first time in the market in 1939, and it seemed that it was bought by King Farouk.
It is estimated at two to three million Swiss francs.
