And the Queen's preference also had a deeper meaning, as the paper reported that there were issues around the origin of the tiara Meghan had preferred for her wedding day.
“The provenance of the tiara could not be established,” the source told The Sun.
“There were concerns it could have come from Russia originally.”
Meghan went on to wear the Queen Mary diamond bandeau tiara, which was lent to her by the Queen.
"The diamond bandeau is English and was made in 1932, with the entre brooch dating from 1893," revealed a statement from Kensington Palace.
"The bandeau, which is made of diamonds and platinum, is formed as a flexible band of eleven sections, pierced with interlaced ovals and pavé set with large and small brilliant diamonds. The centre is set with a detachable brooch of ten brilliant diamonds.
"The diamond bandeau was made for Queen Mary and specifically designed to accommodate the centre brooch. This brooch was given as a present to the then Princess Mary in 1893 by the County of Lincoln on her marriage to Prince George, Duke of York. The bandeau and the brooch were bequeathed by Queen Mary to The Queen in 1953."
As per royal tradition, her wedding day was the first time Meghan was permitted to wear a tiara.
