Royal brides are traditionally loaned priceless heirlooms to wear on their wedding day.
Meghan could have chosen the Spencer tiara - famously worn by Harry’s later mother Diana, Princess of Wales when she married the Prince of Wales in 1981.
But Meghan has instead selected this little known piece, which features a magnificent floral-shaped suspended brooch in the centre made of a large round diamond surrounded by nine smaller circular diamonds.
It was specifically made for the Queen’s grandmother Queen Mary in 1932 to accommodate the detachable brooch, which was given to Mary as a wedding present in 1893 by the County of Lincoln.
The bandeau is a flexible band of 11 intricate glittering sections, pierced with interlaced ovals and pave set with large and small brilliant diamonds.
The bandeau and the brooch were bequeathed by Queen Mary to her granddaughter the Queen on her death in 1953.
