The handiwork of New York jeweller Tiffany & Co., this fabulous yellow diamond was worn by Hollywood icon Audrey Hepburn in 1961 in publicity photographs for the film Breakfast At Tiffany's. The 128.54-carat diamond was cut in 1888 and is still owned by the company.

Apart from Audrey Hepburn, only four other women have worn the stone: Beyoncé, Lady Gaga (pictured), Gal Gadot, and Mrs Mary Whitehouse, the wife of an American diplomat.
